Gynecologic Oncology Practice Questions

Q: Which one of the following is NOT a mandatory procedure for FIGO staging of Carcinoma cervix?

Ultrasound abdomen. ***Ultrasound abdomen*** - **Ultrasound abdomen** is **not a mandatory procedure** for the standard FIGO staging of cervical carcinoma. - FIGO staging is primarily a **clinical staging system** based on physical examination, inspection, palpation, and biopsy. - While imaging studies (CT, MRI, ultrasound) are valuable for **treatment planning**, they are not part of the official FIGO staging criteria. - Optional procedures allowed include cystoscopy, proctoscopy, and IVP, but not routine abdominal ultrasound. *Biopsy* - A **tissue biopsy** with histological confirmation is **mandatory** for the diagnosis and staging of cervical carcinoma. - It establishes the presence of malignancy and determines the histological type (squamous cell carcinoma, adenocarcinoma, etc.). - Without biopsy confirmation, no staging can be performed. *Pelvic examination* - A thorough **pelvic examination** (including inspection, palpation, and speculum examination) is **mandatory** and forms the cornerstone of FIGO staging. - Clinical assessment determines tumor size, vaginal involvement, parametrial extension, and pelvic wall involvement. - FIGO staging is primarily a **clinical staging system**, making pelvic examination essential. *Endocervical curettage* - **Endocervical curettage (ECC)** is **not mandatory** for FIGO staging of invasive cervical carcinoma. - ECC is primarily used in the evaluation of **cervical dysplasia/CIN** to rule out occult endocervical involvement. - Once invasive carcinoma is confirmed by biopsy, ECC does not contribute to staging and is not part of standard FIGO protocols. - However, it may be performed in specific clinical scenarios at the physician's discretion, but it remains optional.

Q: Consider the following statements regarding Carcinoma Cervix: 1. Clinical staging is done 2. Treatment if provided in stage I leads to survival rate of 80–90 % 3. Surgery is preferred in young women with stage III disease 4. HPV is considered to be the causative agent Which of the statements given above are correct?

1, 2 and 4 only. ***1, 2 and 4 only*** - **Clinical staging** is the primary method for staging cervical cancer using the FIGO system, as opposed to surgical staging used for other gynecological cancers. - Early detection and treatment in **Stage I** cervical cancer offer excellent prognoses, with survival rates often reported between **80-90%**. - **Human Papillomavirus (HPV)** is the established causative agent for nearly all cases of cervical cancer, particularly high-risk subtypes like HPV-16 and HPV-18. *1, 2, 3 and 4* - This option is incorrect because it includes statement 3, which is false. - **Stage III** cervical cancer represents locally advanced disease with parametrial involvement or pelvic wall extension, making it unsuitable for primary surgical management. - Stage III disease is managed with **concurrent chemoradiation** (cisplatin-based chemotherapy with external beam radiation and brachytherapy), not surgery, regardless of patient age. *3 and 4 only* - This option is incorrect as it includes the false statement 3 about surgery in Stage III disease. - It also omits the correct statements regarding **clinical staging** (statement 1) and the excellent **survival rates** in Stage I (statement 2). *1 and 2 only* - This option is incomplete as it correctly identifies that **clinical staging** is used and that **Stage I treatment offers good survival**. - However, it fails to include statement 4, which correctly identifies **HPV as the causative agent** of cervical cancer—a fundamental fact in cervical cancer etiology.

Q: Which of the following are the vaccines for prevention of cervical cancer? 1. Cervarix 2. Gardasil 3. T-dap 4. Influenza Select the correct answer using the code given below:

1 and 2. ***Option A: 1 and 2 (Cervarix and Gardasil)*** - Both are **HPV vaccines** that prevent cervical cancer by targeting oncogenic human papillomavirus types - **Cervarix**: Bivalent vaccine protecting against HPV-16 and HPV-18 (responsible for ~70% of cervical cancers) - **Gardasil**: Quadrivalent vaccine (Gardasil-4) protecting against HPV-6, 11, 16, and 18; Nonavalent version (Gardasil-9) covers additional high-risk HPV types (31, 33, 45, 52, 58) - **Clinical significance**: Persistent HPV infection is the primary cause of cervical cancer; vaccination is primary prevention *Option B: 1 and 3* - While Cervarix is correct, **T-dap vaccine** (tetanus, diphtheria, acellular pertussis) is a bacterial vaccine with no role in cervical cancer prevention - T-dap targets entirely different pathogens and has no effect on HPV infection *Option C: 2 and 3* - Gardasil is correct for cervical cancer prevention, but **T-dap** is unrelated to HPV or cervical cancer - Mixing a correct HPV vaccine with an unrelated bacterial vaccine makes this option incorrect *Option D: 2 and 4* - Gardasil is correct, but **influenza vaccine** targets influenza virus to prevent seasonal flu, not HPV-related malignancies - Influenza vaccine has no protective effect against cervical cancer

Q: The most common site of cervical cancer is:

Transformation zone. ***Transformation zone*** - The **transformation zone** is where the squamous epithelium of the **ectocervix** meets the columnar epithelium of the **endocervix**. - This area is highly susceptible to **human papillomavirus (HPV) infection**, which is the primary cause of cervical cancer, making it the most common site of origin. *Endocervix* - The **endocervix** is lined by columnar epithelium and primarily gives rise to **adenocarcinoma**, which is less common than squamous cell carcinoma. - While cervical cancer can occur here, it is not the most frequent site of origin for all types of cervical cancer. *Isthmus* - The **isthmus** is the narrow lower part of the uterus, superior to the cervix. - It is not a primary site for the development of cervical cancer; cancerous changes typically originate within the cervical regions proper. *Ectocervix* - The **ectocervix** is the vaginal portion of the cervix, covered by stratified squamous epithelium. - While **squamous cell carcinomas** frequently occur in the cervix, they mostly originate in the transformation zone, not the ectocervix itself.

Q: Tumor marker of epithelial ovarian carcinoma is:

CA-125. ***CA-125*** - **CA-125 (Cancer Antigen 125)** is the most widely used and validated tumor marker for detecting and monitoring **epithelial ovarian carcinoma**. - Elevated levels are found in approximately 80% of women with epithelial ovarian cancer, making it useful in guiding treatment decisions and assessing recurrence. *Alpha feto protein* - **Alpha-fetoprotein (AFP)** is primarily elevated in **germ cell tumors** of the ovary (e.g., endodermal sinus tumor) or in hepatocellular carcinoma and some testicular cancers, not epithelial ovarian carcinoma. - Its presence usually indicates a different histological subtype of ovarian malignancy. *Beta HCG* - **Beta-human chorionic gonadotropin (β-hCG)** is a tumor marker utilized for detecting **germ cell tumors**, particularly **choriocarcinoma** and some embryonal carcinomas, as well as pregnancy. - It is not typically elevated in epithelial ovarian carcinoma. *LDH* - **Lactate dehydrogenase (LDH)** is a general marker of **tissue damage or high cell turnover**, elevated in many cancers, including dysgerminoma (an ovarian germ cell tumor), but it is not specific for epithelial ovarian carcinoma. - Due to its lack of specificity, LDH alone is not considered the primary tumor marker for epithelial ovarian cancer.

Q: What is the age group distribution for vulval cancer?

Both age groups (35-55 and 65-85 years). ***Both age groups (35-55 and 65-85 years)*** - Vulval cancer demonstrates a **bimodal age distribution**, meaning it presents with two distinct peaks of incidence. - The first peak occurs in younger women, typically aged **35-55 years**, often associated with **HPV infection** and vulvar intraepithelial neoplasia (VIN). - The second peak is seen in older women, aged **65-85 years**, where the disease is more commonly linked to **chronic inflammatory conditions** such as lichen sclerosus, often without HPV involvement. - This bimodal pattern reflects the **two distinct pathogenic pathways** of vulval cancer: HPV-related and non-HPV-related disease. *65-85 years* - While this age group represents a significant peak of vulval cancer incidence, particularly in cases **unrelated to HPV**, it does not encompass the entire distribution. - Focusing solely on this age range would **miss cases occurring in younger women**, which are increasingly recognized due to HPV-related disease. *35-55 years* - This age group does indeed represent a distinct peak for vulval cancer, especially in cases linked to **Human Papillomavirus (HPV) infection**. - However, ignoring the incidence in older women would provide an **incomplete understanding** of the disease's overall epidemiology. *Not age specific* - Vulval cancer is definitely **age-specific** with distinct age group distributions. - The incidence is **not uniformly distributed** across all ages but rather shows an increased likelihood within specific age ranges, demonstrating clear bimodal peaks.

Q: The following set of instruments are used for which procedure?

Pap smear. ***Pap smear*** - The image displays a complete set of instruments used for a **Pap smear**, including **glass slides** for sample collection, a **cervical brush**, a **spatula** (cytobrush and Ayre spatula), and a **speculum** to visualize the cervix. - These tools are specifically designed for collecting cervical cells to screen for **cervical cancer** and **precancerous changes**. *Biopsy* - A biopsy typically involves specialized instruments like **punch biopsy tools**, **forceps**, or needles to extract tissue samples, which are not depicted here. - While glass slides might be used for processing biopsy samples, the primary collection tools are absent. *Dilatation and curettage* - This procedure requires instruments such as **dilators** to open the cervix and **curetters** to scrape the uterine lining, which are not shown in the image. - The instruments shown are for surface cell collection, not for uterine cavity procedures. *Hysteroscopy* - Hysteroscopy uses a **hysteroscope**—a thin, lighted tube with a camera—to visualize the inside of the uterus. - The instruments in the image are for external examination and cervical cell collection, not for direct visualization of the uterine cavity.

Q: Arrange the following in sequential order with regards to the steps of collection of samples for pap smear testing: Use posterior vaginal wall retractor Take the sample Make smear on a slide Fix the smear

1,2,3,4. ***1,2,3,4*** - The correct sequence for collecting a Pap smear involves first **visualizing the cervix** using a posterior vaginal wall retractor, then **taking the sample** (e.g., using a broom or spatula and brush), followed by **making a smear on a slide** and finally **fixing the smear** to preserve the cells. - This sequential order ensures proper cell collection and preservation for accurate cytological examination. *1,2,4,3* - This option incorrectly places **fixing the smear** before **making the smear on the slide**. Cells must first be spread onto the slide before they can be fixed. - Fixing an un-smeared sample or attempting to smear after fixing would lead to an inadequate or damaged specimen. *3,1,2,4* - This sequence incorrectly starts with **making a smear on a slide** before any sample has been collected or the cervix visualized. - One cannot make a smear without first taking a sample and accessing the cervix via a retractor. *2,1,3,4* - This option incorrectly states that **taking the sample** occurs before **using a posterior vaginal wall retractor**. The retractor is essential for proper visualization and access to the cervix to obtain a quality sample. - Attempting to take a sample without proper visualization would lead to an inadequate or incorrect specimen collection.

Q: A 32-year-old HIV-positive woman with CD4 count 180/µL presents with extensive genital warts resistant to conventional therapy. Recent Pap smear shows HSIL. Which management approach is most appropriate?

Immediate colposcopy and surgical excision. ***Immediate colposcopy and surgical excision*** - Given the patient's **HIV-positive status**, **low CD4 count**, extensive and resistant **genital warts**, and **HSIL on Pap smear**, there is a high likelihood of advanced or rapidly progressing cervical intraepithelial neoplasia or early invasive carcinoma. - **Colposcopy** allows for direct visualization and targeted biopsies, while **surgical excision** (e.g., LEEP or cold knife conization) can effectively remove both the HSIL and resistant warts, which is crucial in immunocompromised patients. *Observation and repeat Pap in 6 months* - This approach is inappropriate due to the patient's **immunocompromised state** (low CD4 count), which predisposes her to more aggressive and rapidly progressive **HPV-related disease**. - **HSIL** in an HIV-positive patient warrants immediate investigation and intervention, not delayed follow-up, as the risk of progression to **invasive cancer** is significantly higher. *Topical imiquimod alone* - **Imiquimod** is an immune-response modifier used for external genital warts, but it is unlikely to be sufficient for extensive, resistant warts, especially in an **immunocompromised host**. - It does not directly address the underlying **HSIL**, which requires histological evaluation and potential excisional treatment to prevent progression to cancer. *Podophyllin application weekly* - **Podophyllin** is a cytotoxic agent used for external genital warts, but it is generally reserved for smaller lesions and requires careful application due to its potential toxicity. - It is **contraindicated in pregnancy** and not recommended for internal lesions or for treating or preventing the progression of **HSIL**, which requires a more definitive management.
