Breast Surgery Practice Questions

Q: Which one of the following is not a correct statement with reference to locally advanced carcinoma breast ?

Radical Mastectomy is the treatment of choice. *Patients are staged as T3 or T4 with any N, without distant metastasis (M0)* - **Locally advanced breast cancer (LABC)** is correctly defined as tumors that are **T3 or T4** or involve regional lymph nodes (**any N**) without distant metastasis (**M0**). - This statement is **correct** regarding LABC staging criteria. *It constitutes the bulk of patients of carcinoma breast in India* - This statement is **correct**. In India, approximately **50-60% of breast cancer patients present with locally advanced disease** at the time of diagnosis. - This is in stark contrast to Western countries where LABC represents less than 10% of cases. - The high prevalence is attributed to lack of screening programs, delayed presentation, limited awareness, and socioeconomic factors. *Neoadjuvant chemotherapy downgrades the disease* - This statement is **correct**. **Neoadjuvant chemotherapy (NACT)** is a cornerstone of LABC management. - NACT aims to **downstage** the tumor, making it more amenable to surgical resection and increasing the feasibility of breast-conserving surgery. - It also provides early treatment of micrometastases and serves as an in vivo test of tumor chemosensitivity. ***Radical Mastectomy is the treatment of choice*** - This statement is **INCORRECT** and is the correct answer to this negation question. - **Radical mastectomy (Halsted mastectomy)** involving removal of breast, pectoral muscles, and axillary nodes is **no longer the standard treatment** for LABC. - Modern treatment involves a **multimodal approach**: neoadjuvant chemotherapy followed by **modified radical mastectomy (MRM)** or breast-conserving surgery with radiation therapy. - MRM preserves the pectoral muscles, providing better functional and cosmetic outcomes while maintaining oncological safety.

Q: The inflammatory breast carcinoma is staged as

T4d. ***T4d*** - **Inflammatory breast carcinoma** is by definition a **T4d tumor** in the TNM staging system, regardless of tumor size. - This designation reflects the aggressive nature and characteristic features of erythema and edema involving a substantial portion of the breast. *T4c* - **T4c** refers to either **T4a** (chest wall invasion) and **T4b** (ulceration, edema, or skin nodules) combined. - While these can be features of advanced breast cancer, they do not specifically define inflammatory breast carcinoma. *T1a* - **T1a** describes a tumor size of **greater than 0.5 cm but not more than 1 cm** in greatest dimension. - Inflammatory breast carcinoma is not staged based on tumor size in this manner due to its diffuse nature. *T1b* - **T1b** describes a tumor size of **greater than 1 cm but not more than 2 cm** in greatest dimension. - Inflammatory breast carcinoma is characterized by diffuse involvement of the breast skin and does not fit into typical size-based T categories like T1b.

Q: Following radical surgery for the carcinoma of breast, reconstruction of the breast can be performed by using the following procedures except

Deltopectoral flap. ***Deltopectoral flap*** - The **deltopectoral flap**, also known as the Bakamjian flap, is primarily used for **head and neck reconstruction**, particularly for defects in the pharynx, esophagus, or oral cavity. - It involves tissue from the shoulder and chest wall, but its design and vascular supply make it unsuitable for **breast reconstruction** after radical mastectomy, which requires significantly more volume and different tissue characteristics. *Silicone implants* - **Silicone implants** are a common method for breast reconstruction, offering a less invasive option than flap procedures. - They are placed either beneath the pectoral muscle or subcutaneously to restore breast volume and shape. *Transversus abdominis muscle flap (TRAM flap)* - The **TRAM flap** is a widely used and versatile autologous tissue reconstruction method, utilizing tissue from the lower abdomen to create a new breast mound. - It can be either pedicled (retaining its original blood supply) or free (requiring microvascular anastomosis), providing a natural-feeling and long-lasting reconstruction. *Latissimus dorsi flap (LD flap)* - The **latissimus dorsi (LD) flap** involves transferring muscle, fat, and skin from the back to the chest to reconstruct the breast. - It is particularly useful for smaller breasts or when combined with an implant, and it can provide good aesthetic results with reliable blood supply.

Q: The most common site of skeletal metastases in carcinoma of the breast is

Thoracic vertebrae. ***Thoracic vertebrae*** - The **thoracic spine** accounts for **68-80%** of all spinal metastases in breast cancer due to direct venous drainage via **Batson's venous plexus** through the **azygos vein** and **intercostal veins**. - The **valveless nature** of Batson's plexus allows **retrograde seeding** of tumor cells, making thoracic vertebrae the primary target for skeletal metastases. *Skull* - While skull metastases can occur in breast cancer, they represent a **less frequent site** compared to the axial skeleton, particularly thoracic vertebrae. - Skull involvement typically presents as **lytic lesions** and may cause neurological symptoms, but occurs in a minority of cases. *Pelvis* - The pelvis is indeed a common site for bone metastases in breast cancer, but it is **secondary** to thoracic vertebral involvement. - Pelvic metastases can cause **pathological fractures** and hip pain, but represent a smaller percentage of initial skeletal spread. *Lumbar vertebrae* - Lumbar spine involvement occurs in only **16-22%** of spinal metastases, significantly **less frequent** than thoracic vertebrae. - This distinction is crucial for exam purposes as lumbar involvement is often confused with thoracic, but the **anatomical drainage pattern** clearly favors thoracic spread.

Q: A patient has a 6-cm breast tumor with mobile, clinically positive, ipsilateral axillary lymph nodes and no evidence of distant metastasis. The stage of the breast cancer is

Stage IIIa. ***Stage IIIa*** - A **6-cm tumor (T3)** with **mobile, clinically positive ipsilateral axillary lymph nodes (N1)** and **no distant metastasis (M0)** classifies as **T3N1M0 = Stage IIIA** according to AJCC TNM staging. - Stage IIIA includes **T3N1M0** among other combinations, representing locally advanced breast cancer with significant tumor burden and regional nodal involvement. *Stage IIb* - Stage IIB is classified as **T2N1M0** (2-5 cm tumor with mobile axillary nodes) or **T3N0M0** (>5 cm tumor with no nodal involvement). - This patient has **T3N1M0**, which exceeds Stage IIB criteria due to the combination of large tumor size and positive lymph nodes. *Stage I* - Stage I involves **small tumors (T1, ≤2 cm)** with **no lymph node involvement (N0)** or only micrometastases. - The **6-cm tumor size** and **clinically evident axillary lymph node involvement** far exceed Stage I parameters. *Stage IIIb* - Stage IIIB requires **T4 disease** with chest wall invasion, skin involvement (ulceration, satellite nodules), or inflammatory breast cancer features. - This case shows **T3 disease** without signs of **locally advanced features** like chest wall fixation or skin changes.

Q: Which of the following does not alter the T stage in breast cancer?

Nipple retraction. ***Nipple retraction*** - Nipple retraction, while a significant clinical sign that can indicate an underlying malignancy, does **not alter the T stage** (tumor size and extent) of breast cancer. - It is considered a local sign of tumor proximity or involvement but does not classify the tumor into a T4 category according to AJCC TNM staging. - Nipple retraction may be seen with various T stages and is **not a criterion for upstaging**. *Pectoral muscle involvement* - **Important note**: Involvement of the **pectoralis muscle alone does NOT alter T stage** according to current AJCC TNM classification. - Only **chest wall involvement** (ribs, intercostal muscles, serratus anterior) qualifies as **T4b**. - This is a common point of confusion, but pectoralis muscle is **not considered chest wall** for staging purposes. *Skin ulceration* - **Skin ulceration** directly reflects tumor invasion through the skin of the breast. - This finding is a criterion for classifying the tumor as **T4b**, indicating advanced local disease. - Clearly **alters the T stage** regardless of tumor size. *Peau d'orange* - **Peau d'orange** (orange peel appearance) is caused by obstruction of dermal lymphatics by tumor cells, leading to **skin edema**. - This sign is a criterion for classifying the tumor as **T4b** (edema of the skin including peau d'orange). - Clearly **alters the T stage** and indicates advanced local disease.

Q: Which of the following is NOT correct for breast abscess?

A counterincision is made in the dependant part. ***A counterincision is made in the dependant part*** - **Counterincisions** are generally *not* required for breast abscesses as a single **radial incision** is usually sufficient for adequate drainage. - Making additional incisions can damage the **ductal architecture** and increase the risk of **fistula formation** and poor cosmetic outcomes. *Dressings are changed frequently* - **Frequent dressing changes** are essential after abscess drainage to remove **exudate** and monitor healing progress. - This prevents secondary infection and allows the cavity to heal from the **inside out** properly. *Antibiotic is given if pus is already present* - **Antibiotics** are indicated even when pus is present, as they treat the underlying **bacterial infection** and prevent spread. - They work synergistically with surgical drainage to ensure complete resolution and prevent **recurrence**. *Drainage of abscess by a radial incision* - **Radial incisions** are the gold standard as they follow the natural **ductal pattern** of the breast tissue. - This approach minimizes damage to **milk ducts** and provides better cosmetic results compared to circumferential incisions.

Q: Mondor’s disease is

Thrombophlebitis of superficial veins of breast. ***Thrombophlebitis of superficial veins of breast*** - Mondor's disease is characterized by **thrombophlebitis**, which is inflammation and clotting, of the **superficial veins of the breast** and sometimes the chest wall. - It often manifests as a **palpable, tender cord-like structure** under the skin. *Multiple breast cysts* - This condition involves the presence of **fluid-filled sacs** within the breast tissue, which can be palpable but do not present as a classic cord-like structure. - Cysts are typically smooth, mobile, and can fluctuate in size with the **menstrual cycle**, unlike Mondor's disease. *Eczema by nipple and areola* - This refers to an **inflammatory skin condition** affecting the **nipple and areola**, characterized by redness, itching, scaling, and sometimes oozing. - It is a **dermatological issue** and does not involve vascular clotting or a palpable cord. *Lymphangitis of mammary lymphatics* - **Lymphangitis** is the inflammation of **lymphatic vessels**, often presenting as red streaks and tenderness. - While it can affect the breast, it involves the **lymphatic system** rather than the superficial venous system and would not typically present as a thrombosed vessel.
