Smooth Muscle Tumors of the Vulva: Symptoms & Treatment

Smooth muscle tumors of the vulva represent a rare subset of vulvar neoplasms, often presenting diagnostic and therapeutic challenges for healthcare professionals. Leiomyosarcomas, one specific type of smooth muscle tumor, exhibit aggressive behavior and necessitate prompt intervention. The International Society for the Study of Vulvovaginal Disease (ISSVD) provides classification systems and guidelines crucial for accurate diagnosis and management of these tumors. Symptoms of smooth muscle tumors of the vulva can vary, potentially mimicking other more common vulvar conditions, thereby requiring thorough clinical evaluation and advanced imaging techniques, such as magnetic resonance imaging (MRI), to distinguish them from benign lesions.

Smooth muscle tumors arising in the vulva represent a rare and often challenging clinical entity. These tumors originate from the smooth muscle tissue present in the vulvar region, including the walls of blood vessels and the arrector pili muscles of hair follicles. Due to their infrequent occurrence, understanding their nature, diagnosis, and management is crucial for healthcare professionals.

Defining Smooth Muscle Tumors and Their Rarity

Smooth muscle tumors of the vulva are neoplasms arising from the involuntary muscle tissue found within this anatomical region. These tumors are classified based on their biological behavior, with leiomyomas representing the benign form and leiomyosarcomas signifying the malignant counterpart.

Given the relatively small amount of smooth muscle tissue in the vulva compared to other regions of the body, these tumors are considered rare. Accurate epidemiological data are limited, but studies suggest that they account for a very small percentage of all vulvar neoplasms. This rarity underscores the importance of considering these tumors in the differential diagnosis of vulvar lesions.

Distinguishing Between Leiomyoma and Leiomyosarcoma

The distinction between leiomyoma and leiomyosarcoma is critical for determining patient prognosis and treatment strategies. Leiomyomas are benign tumors characterized by slow growth, well-defined borders, and a low risk of recurrence or metastasis. They typically present as painless or mildly symptomatic masses.

In contrast, leiomyosarcomas are malignant tumors exhibiting aggressive growth, poorly defined margins, and a significant potential for local invasion and distant metastasis. Microscopic examination is essential to differentiate between these two entities. Pathological features such as cellular atypia, mitotic activity, and necrosis are used to determine the tumor's malignant potential. Immunohistochemical staining can also aid in distinguishing between leiomyoma and leiomyosarcoma.

The accurate classification relies heavily on the expertise of the pathologist who examines the tissue sample obtained from biopsy or surgical excision.

The Significance of Early Diagnosis and Intervention

Early diagnosis plays a pivotal role in improving patient outcomes for smooth muscle tumors of the vulva. When detected at an early stage, leiomyomas can often be managed with conservative surgical excision, leading to a high likelihood of complete remission.

For leiomyosarcomas, early diagnosis allows for more effective treatment options, including wide local excision, radiation therapy, and chemotherapy. Early diagnosis of leiomyosarcoma increases the chances of successful treatment and long-term survival.

Delay in diagnosis can lead to tumor progression, increased local invasion, and a higher risk of metastasis, thereby compromising treatment outcomes and overall survival. Therefore, prompt evaluation of vulvar masses and suspicious lesions is essential for timely intervention and improved patient care.

Following our introduction to the nature and significance of smooth muscle tumors in the vulva, it is imperative to delve into the factors that contribute to their development. Understanding the etiology and identifying potential risk factors are critical steps toward improving prevention strategies and personalized patient care.

Etiology and Risk Factors: What Causes These Tumors?

The precise cause of smooth muscle tumors of the vulva remains elusive, reflecting the complexity of tumorigenesis. However, research suggests a multifactorial etiology, encompassing genetic predispositions, environmental influences, and potential associations with pre-existing gynecological conditions.

Unraveling these factors is crucial for identifying at-risk individuals and developing targeted interventions.

Genetic Predisposition

While smooth muscle tumors of the vulva are not typically considered hereditary cancers, genetic factors may play a role in their development. Certain genetic mutations or polymorphisms might increase an individual's susceptibility to these tumors.

Further research is needed to identify specific genes or genetic pathways involved in the tumorigenesis of vulvar smooth muscle tumors.

One area of interest is the potential link between smooth muscle tumor development and mutations in genes involved in DNA repair, cell cycle regulation, and growth factor signaling.

Future studies exploring the genetic profiles of affected individuals may reveal novel insights into the underlying mechanisms of these tumors.

Environmental Exposures

Environmental factors have been implicated in the development of various cancers, and their potential contribution to smooth muscle tumors of the vulva warrants investigation. Exposure to certain chemicals, radiation, or other environmental toxins could potentially damage cellular DNA and increase the risk of tumorigenesis.

Research is needed to identify specific environmental exposures that may be associated with smooth muscle tumors of the vulva.

For example, studies could explore the potential role of occupational exposures, lifestyle factors (such as smoking or diet), and exposure to environmental pollutants in the development of these tumors.

Understanding the impact of environmental factors could lead to preventive strategies aimed at reducing exposure to potential carcinogens.

Correlation with Pre-existing Gynecological Conditions

The association between smooth muscle tumors of the vulva and pre-existing gynecological conditions is an area of ongoing investigation. Some studies have suggested a possible link between these tumors and conditions such as leiomyomas in the uterus or other benign gynecological disorders.

Whether these associations reflect a shared underlying etiology or simply represent coincidental occurrences remains unclear.

Investigating the potential interplay between pre-existing gynecological conditions and the development of smooth muscle tumors of the vulva could provide valuable insights into the pathogenesis of these tumors.

Further research is needed to elucidate the nature and significance of these correlations. This should include studies examining the hormonal and molecular profiles of affected individuals.

Understanding the factors that contribute to the development of smooth muscle tumors of the vulva is essential for improving prevention, early detection, and personalized treatment strategies.

Future research should focus on elucidating the genetic, environmental, and clinical factors involved in the tumorigenesis of these rare tumors.

Such efforts will ultimately lead to improved outcomes and enhanced quality of life for affected individuals.

Following our introduction to the nature and significance of smooth muscle tumors in the vulva, it is imperative to delve into the factors that contribute to their development. Understanding the etiology and identifying potential risk factors are critical steps toward improving prevention strategies and personalized patient care.

Diagnosis and Evaluation: Identifying and Characterizing the Tumor

The accurate diagnosis and characterization of smooth muscle tumors of the vulva are paramount for effective treatment planning and ultimately, patient prognosis. The diagnostic process is multifaceted, integrating clinical assessment, advanced imaging techniques, and detailed pathological evaluation.

Each step plays a crucial role in distinguishing between benign and malignant lesions, determining the extent of the disease, and guiding therapeutic interventions.

Initial Presentation and Physical Findings

The initial presentation of a smooth muscle tumor of the vulva can vary significantly. Patients may present with a palpable mass or swelling in the vulvar region. This may or may not be associated with pain or discomfort.

Other symptoms can include itching, bleeding, or changes in the skin's appearance. Some patients may be asymptomatic, with the tumor detected during a routine gynecological examination. A thorough physical examination is critical for identifying any abnormalities.

Key findings during the examination may include the size, location, and consistency of the mass, as well as any signs of ulceration or inflammation.

Colposcopy in Initial Assessment

Colposcopy, a procedure involving the use of a magnifying instrument to visualize the vulvar, vaginal, and cervical tissues, plays a role in the initial assessment. While not specifically designed for diagnosing smooth muscle tumors, colposcopy can help identify suspicious areas that warrant further investigation, such as biopsy.

Colposcopy allows for a magnified view of the vulvar surface, aiding in the detection of subtle changes or abnormalities. This is especially helpful in differentiating smooth muscle tumors from other vulvar lesions.

Directed biopsies can be performed on any suspicious areas identified during colposcopy.

Biopsy: Histological Confirmation and Grading

The cornerstone of diagnosing smooth muscle tumors of the vulva is a biopsy. A biopsy involves the removal of a small tissue sample from the suspicious area for microscopic examination. This is crucial for confirming the diagnosis and determining whether the tumor is benign (leiomyoma) or malignant (leiomyosarcoma).

The biopsy sample is then processed and examined by a pathologist, who assesses the cellular characteristics of the tumor.

In addition to confirming the diagnosis, the biopsy allows for grading of the tumor, which is an assessment of how aggressive the cancer cells appear under the microscope.

The grade is an important prognostic factor, with higher-grade tumors being more likely to grow and spread rapidly.

Pathology Reports: Atypia and Mitotic Rate

The pathology report provides detailed information about the characteristics of the tumor. Two key components of the pathology report are atypia and mitotic rate.

Atypia refers to abnormalities in the appearance of the tumor cells. This can include variations in cell size, shape, and nuclear features.

Significant atypia is often associated with malignant tumors. Mitotic rate refers to the number of cells that are actively dividing in a given area of the tumor tissue. A high mitotic rate indicates rapid cell growth and proliferation, which is also characteristic of malignant tumors.

These two factors (Atypia and Mitotic Rate) are used to help differentiate benign from malignant tumors, and also to grade malignant tumors.

Immunohistochemistry: Differentiating Tumor Types

Immunohistochemistry (IHC) is a technique that uses antibodies to identify specific proteins in the tumor cells. It can be particularly useful in differentiating smooth muscle tumors from other types of soft tissue tumors that may occur in the vulva.

By identifying the presence or absence of certain proteins, immunohistochemistry can help confirm the diagnosis of a smooth muscle tumor and distinguish it from other spindle cell lesions.

Common markers used in immunohistochemistry for smooth muscle tumors include smooth muscle actin (SMA), desmin, and caldesmon.

MRI: Assessing Tumor Size and Local Invasion

Magnetic resonance imaging (MRI) is a valuable imaging modality for assessing the size, location, and extent of local invasion of smooth muscle tumors of the vulva. MRI provides detailed images of the soft tissues, allowing for accurate visualization of the tumor and its relationship to surrounding structures.

MRI is particularly useful for determining whether the tumor has spread to adjacent tissues, such as the vagina, perineum, or pelvic muscles.

This information is essential for surgical planning and determining the appropriate treatment strategy.

CT Scans: Evaluating for Distant Metastasis

Computed tomography (CT) scans are primarily used to evaluate for distant metastasis. CT scans provide cross-sectional images of the body, allowing for the detection of tumors in other organs, such as the lungs, liver, or bones.

While smooth muscle tumors of the vulva are relatively rare to metastasize, CT scans are recommended for patients with high-grade tumors or those with clinical signs or symptoms suggestive of metastatic disease.

Pathology Labs: Processing and Analyzing Tissue Samples

Pathology labs play a central role in the diagnosis and characterization of smooth muscle tumors of the vulva. These labs are responsible for processing the biopsy and surgical specimens, preparing them for microscopic examination.

Pathology lab personnel embed the tissue samples in paraffin wax, section them into thin slices, and stain them with special dyes to highlight cellular structures. They also perform immunohistochemical studies and other specialized tests to further characterize the tumor.

The pathologist then examines the stained slides under a microscope to render a diagnosis.

The Microscope: A Cornerstone of Pathological Examination

The microscope is an indispensable tool in the pathological examination of smooth muscle tumors of the vulva. Pathologists use microscopes to visualize the cellular details of the tumor tissue, assessing the size, shape, and arrangement of the cells, as well as the presence of any abnormalities.

Microscopic examination is essential for differentiating benign from malignant tumors, grading malignant tumors, and identifying specific features that may influence treatment decisions.

The information gathered from microscopic examination is then compiled into a pathology report, which serves as the basis for clinical management.

The information gleaned from this comprehensive diagnostic process enables clinicians to make informed decisions regarding treatment strategies, ultimately striving for optimal outcomes for patients facing these rare and challenging tumors.

Following our discussion of diagnosis and evaluation, it is essential to understand how the extent of the disease is determined. This process, known as staging, is fundamental to guiding treatment decisions and predicting patient outcomes.

Staging: Determining the Extent of the Disease

Once a smooth muscle tumor of the vulva has been diagnosed, the next critical step is to determine the extent of the disease. This process, known as staging, is vital for tailoring treatment strategies and predicting prognosis.

The most widely used system for staging vulvar cancers, including leiomyosarcomas, is the TNM staging system developed by the American Joint Committee on Cancer (AJCC).

Understanding the TNM Classification System

The TNM system is based on three key components:

• T (Tumor): Describes the size and extent of the primary tumor.

• N (Nodes): Indicates whether the cancer has spread to regional lymph nodes.

• M (Metastasis): Determines whether the cancer has metastasized to distant sites.

T Category: Assessing the Primary Tumor

The T category is further subdivided based on the size and location of the tumor within the vulva. Smaller tumors confined to the vulva generally have a better prognosis than larger tumors that have spread to adjacent structures.

Specific T classifications include:

• T1: Tumor limited to the vulva or perineum and ≤ 2 cm in greatest dimension.

• T2: Tumor limited to the vulva or perineum and > 2 cm in greatest dimension.

• T3: Tumor of any size with contiguous spread to the lower urethra, the lower vagina, or the anus.

• T4: Tumor invades any of the following: upper urethra, bladder mucosa, rectal mucosa, is fixed to the pelvic bone, or causes inguinofemoral ulceration or fixed nodes.

N Category: Evaluating Regional Lymph Nodes

The N category assesses the involvement of regional lymph nodes, which are the lymph nodes in the groin area. Lymph node involvement is a significant factor in determining prognosis.

Specific N classifications include:

• N0: No regional lymph node metastasis.

• N1: Unilateral metastasis in regional lymph node(s).

• N2: Bilateral or contralateral metastasis in regional lymph node(s).

M Category: Identifying Distant Metastasis

The M category indicates whether the cancer has spread to distant sites, such as the lungs, liver, or bones. Distant metastasis significantly worsens the prognosis.

The M classification is straightforward:

• M0: No distant metastasis.

• M1: Distant metastasis present.

The Impact of Accurate Staging on Treatment Planning and Prognosis

Accurate staging is crucial for several reasons. First, it helps determine the appropriate treatment strategy.

For example, early-stage tumors may be treated with surgery alone, while more advanced tumors may require a combination of surgery, radiation therapy, and chemotherapy.

Second, staging provides valuable information about prognosis. Patients with early-stage tumors generally have a better prognosis than those with advanced-stage tumors.

The stage of the cancer is one of the most important factors in predicting survival rates.

In summary, the TNM staging system is an essential tool for evaluating the extent of smooth muscle tumors of the vulva. Accurate staging is critical for guiding treatment decisions and providing patients with realistic expectations about their prognosis.

This comprehensive assessment allows for personalized treatment plans aimed at achieving the best possible outcomes.

Treatment Modalities: Available Options for Management

Following a definitive diagnosis and staging of a smooth muscle tumor of the vulva, the focus shifts to devising an appropriate treatment plan. Management strategies are multifaceted and tailored to the specific characteristics of the tumor, the stage of the disease, and the patient's overall health. Treatment options primarily involve surgical interventions, adjuvant therapies, and, critically, a collaborative, multidisciplinary approach.

Surgical Interventions: The Primary Treatment Modality

Surgery is often the cornerstone of treatment, particularly for localized smooth muscle tumors of the vulva. The extent of surgical resection depends largely on the tumor size, location, and the presence of any invasion into surrounding tissues.

Excision and Wide Local Excision

For smaller, well-defined tumors, a simple excision or wide local excision may suffice. These procedures involve removing the tumor along with a margin of healthy tissue to ensure complete eradication of the cancerous cells.

The primary goal is to achieve negative margins, meaning that no cancer cells are detected at the edge of the removed tissue, thus reducing the risk of local recurrence.

Radical Vulvectomy

In cases of larger or more deeply invasive tumors, a more extensive surgical procedure known as a radical vulvectomy may be necessary.

This involves the removal of the entire vulva, including the labia majora, labia minora, and clitoris. Although radical vulvectomy can effectively remove the tumor, it can also have significant functional and cosmetic consequences, impacting the patient's quality of life.

Sentinel Lymph Node Biopsy and Lymphadenectomy: Addressing Lymph Node Involvement

The involvement of regional lymph nodes, particularly the inguinal lymph nodes, is a critical factor in determining the prognosis and guiding treatment decisions. Sentinel lymph node biopsy (SLNB) is a minimally invasive procedure used to assess the presence of cancer cells in the lymph nodes.

In SLNB, a radioactive tracer or blue dye is injected near the tumor site to identify the first lymph node (or nodes) to which cancer cells are likely to spread. This node is then removed and examined under a microscope.

If cancer cells are detected in the sentinel lymph node, a more extensive lymphadenectomy, or surgical removal of the remaining lymph nodes in the groin, may be performed. This is done to prevent further spread of the cancer.

Adjuvant Therapies: Enhancing Treatment Outcomes

Adjuvant therapies, such as chemotherapy and radiation therapy, may be used in conjunction with surgery to improve treatment outcomes, particularly in cases of advanced-stage disease or high-grade tumors.

Chemotherapy

Chemotherapy involves the use of drugs to kill cancer cells throughout the body. It may be administered before surgery (neoadjuvant chemotherapy) to shrink the tumor and make it easier to remove, or after surgery (adjuvant chemotherapy) to eliminate any remaining cancer cells and reduce the risk of recurrence.

Radiation Therapy

Radiation therapy uses high-energy rays to target and destroy cancer cells. It can be delivered externally, using a machine that directs radiation beams at the tumor site, or internally, through the placement of radioactive materials directly into or near the tumor.

Radiation therapy may be used as a primary treatment for tumors that are not amenable to surgical resection, or as an adjuvant therapy after surgery to eradicate any residual disease.

The Critical Role of a Multidisciplinary Approach

Effective management of smooth muscle tumors of the vulva necessitates a multidisciplinary approach involving a team of specialists with expertise in various aspects of cancer care. This team typically includes:

• Gynecologic Oncologists: Specialists in treating cancers of the female reproductive system.

• Surgeons (General or Gynecological): Perform surgical resections.

• Pathologists: Analyze tissue samples to diagnose and classify the tumor.

• Radiologists: Use imaging techniques to guide diagnosis and treatment.

• Oncologists (Medical): Administer chemotherapy and other systemic therapies.

This collaborative approach ensures that all aspects of the patient's care are carefully considered and coordinated, leading to the best possible outcomes.

Specialized Surgical Instruments: Enhancing Precision and Minimizing Morbidity

The use of specialized surgical instruments plays a crucial role in achieving precise tumor removal while minimizing damage to surrounding tissues. These instruments may include:

• Electrocautery devices: To cut and coagulate tissue, reducing blood loss.

• Laparoscopic instruments: For minimally invasive surgical procedures.

• Robotic surgical systems: For enhanced precision and dexterity during complex surgeries.

The choice of surgical instruments depends on the specific characteristics of the tumor, the extent of the surgery, and the surgeon's expertise.

The Multidisciplinary Team: Collaborative Expertise in Management

The successful management of smooth muscle tumors of the vulva hinges on a collaborative, multidisciplinary team. This team brings together specialists from various fields, each contributing unique expertise to ensure comprehensive patient care. The integrated approach, involving gynecologic oncologists, pathologists, radiologists, surgeons, and medical oncologists, optimizes diagnostic accuracy, treatment planning, and overall patient outcomes.

They guide the overall treatment strategy, coordinating care among the various specialists and ensuring that treatment plans are tailored to each patient's unique needs and circumstances. Their expertise is crucial in surgical planning, assessing the need for adjuvant therapies, and managing potential complications.

Pathologists: Unraveling the Tumor's Identity

Pathologists play a pivotal role in the diagnostic process, meticulously analyzing tissue samples obtained through biopsy or surgical resection. Their expertise is essential for confirming the diagnosis of a smooth muscle tumor, differentiating between benign and malignant forms, and determining the tumor's grade and stage.

Through microscopic examination and specialized techniques like immunohistochemistry, pathologists provide critical information about the tumor's characteristics, which informs treatment decisions and helps predict prognosis. The pathology report, with key details like atypia and mitotic rate, is a cornerstone of clinical management.

Radiologists: Guiding Diagnosis and Treatment with Imaging

Radiologists contribute their expertise in diagnostic imaging to visualize the tumor, assess its size and location, and evaluate for any spread to surrounding tissues or distant sites. Imaging modalities like MRI and CT scans provide valuable information that helps guide surgical planning and monitor treatment response.

Radiologists also play a role in image-guided biopsies, assisting in obtaining tissue samples from suspicious areas. Their ability to interpret complex imaging studies is essential for accurate diagnosis and staging.

Surgeons: Executing Precise and Effective Resections

Surgeons, whether general or gynecological, are responsible for surgically removing the tumor. The specific surgical approach depends on the tumor's size, location, and extent of invasion. Surgical options range from wide local excision for smaller, well-defined tumors to radical vulvectomy for more advanced cases.

Surgeons also perform sentinel lymph node biopsies to assess for lymph node involvement. Their skill and precision are crucial for achieving complete tumor removal while minimizing damage to surrounding tissues and preserving function whenever possible.

Medical Oncologists: Managing Systemic Therapies

Medical oncologists specialize in the use of systemic therapies, such as chemotherapy, to treat cancer. They may be involved in the management of smooth muscle tumors of the vulva in cases of advanced-stage disease or high-grade tumors. Chemotherapy may be administered before surgery to shrink the tumor (neoadjuvant chemotherapy) or after surgery to eliminate any remaining cancer cells (adjuvant chemotherapy).

Medical oncologists also manage the side effects of chemotherapy and provide supportive care to patients throughout their treatment. Their expertise is essential for optimizing the effectiveness of systemic therapies and improving patient outcomes.

Prognosis and Follow-Up: Navigating the Post-Treatment Landscape

Following treatment for smooth muscle tumors of the vulva, a comprehensive understanding of prognosis and a meticulous follow-up plan are paramount. These factors directly impact long-term outcomes and quality of life. While the rarity of these tumors can make predicting individual outcomes challenging, several factors have been identified as key determinants of prognosis. A proactive approach to follow-up care is essential for early detection of recurrence and timely intervention.

Key Determinants of Prognosis

Several factors play a crucial role in determining the prognosis for patients with smooth muscle tumors of the vulva. Understanding these factors allows clinicians to tailor follow-up strategies and provide patients with realistic expectations.

Stage at Diagnosis

The stage of the tumor at the time of diagnosis is one of the most significant prognostic indicators. Early-stage tumors, confined to the vulva without lymph node involvement or distant metastasis, generally have a more favorable prognosis than advanced-stage tumors that have spread to regional lymph nodes or other organs.

The TNM (Tumor, Node, Metastasis) staging system, as defined by the American Joint Committee on Cancer (AJCC), is used to classify the extent of the disease. Higher stages are associated with a greater risk of recurrence and a less favorable outcome.

Histologic Grade

The histologic grade of the tumor, as determined by pathological examination, reflects the degree of cellular differentiation and mitotic activity. High-grade tumors, characterized by poorly differentiated cells and a high mitotic rate, tend to be more aggressive and have a higher propensity for recurrence and metastasis.

Conversely, low-grade tumors, which are well-differentiated and have a low mitotic rate, are typically associated with a better prognosis.

Margin Status

Margin status, referring to the presence or absence of cancer cells at the edges of the surgically removed tissue, is another critical factor. Clear margins, meaning that no cancer cells are found at the edge of the resected tissue, indicate a complete surgical removal and are associated with a lower risk of local recurrence.

Positive margins, on the other hand, suggest that some cancer cells may have been left behind, increasing the risk of recurrence.

In cases of positive margins, additional treatment, such as further surgery or radiation therapy, may be necessary.

The Crucial Role of Follow-Up

Regular follow-up examinations and imaging studies are essential for monitoring patients after treatment for smooth muscle tumors of the vulva. The primary goal of follow-up is to detect any signs of recurrence as early as possible, when treatment is most likely to be effective.

Frequency and Components of Follow-Up

The frequency and specific components of follow-up will vary depending on the individual patient's risk factors, stage at diagnosis, and treatment received. However, a typical follow-up schedule may include:

• Physical Examinations: Regular physical examinations of the vulva and surrounding areas to assess for any new or suspicious lesions.
• Pelvic Exams: Pelvic exams to evaluate the overall health of the reproductive organs.
• Imaging Studies: Periodic imaging studies, such as MRI or CT scans, to monitor for recurrence in the vulva, lymph nodes, or distant sites.
• Patient Education: Providing patients with detailed information about potential signs and symptoms of recurrence and encouraging them to report any concerns promptly.

Surveillance for Recurrence

The risk of recurrence is highest within the first few years after treatment. Therefore, more frequent follow-up appointments are typically scheduled during this period.

As time passes without recurrence, the frequency of follow-up appointments may be gradually reduced.

However, it is important to emphasize that long-term surveillance is crucial, as recurrence can occur even many years after initial treatment.

Addressing Recurrence

If recurrence is detected, prompt and aggressive treatment is essential. Treatment options for recurrent smooth muscle tumors of the vulva may include surgery, radiation therapy, chemotherapy, or a combination of these modalities.

The specific treatment approach will depend on the location and extent of the recurrence, as well as the patient's overall health and prior treatment history.
