Lymph nodes in neck

Q) Most common site for lymph node spread is ? (head and neck Onco) 

a) Tongue

b) Lip

c) NAsopharynx

d) Glottis

Ans c

 Primary sites within the pharynx (i.e., nasopharynx, oropharynx, and hypopharynx) and supraglottic larynx  are particularly high risk.

The oral cavity has an intermediate risk,

whereas the glottic larynx, nasal cavity, and paranasal sinuses are low risk. Other predictors of risk of metastases are higher T stage and thickness (in case of oral cavity cancers).

Radio active Iodine in Thyroid Cancer

Q) Which of the following is not true about Radioactive Iodine (RAI) use in thyroid cancer? (Thyroid onco) 

a) Screening with RAI  is less sensitive than Thyroglobulin estimation in most differentiated thyroid cancers for detecting metastasis

b) Metastatic differentiated thyroid carcinoma can be detected by  131I in about 50% of patients

c) Current guidelines s recommend RAI after total thyroidectomy only for patients with known distant metastases

d) Hurthle cell cancer des not take up RAI

 

Bladder Cancer

Q) What is the most suitable treatment option for non muscle-invasive bladder cancer with the risk of recurrences?

A)Cystectomy

B)Intravesical chemotherapy

C)Transurethral resection and adjuvant intravesical chemotherapy

D)Palliative therapy

Answer-C(Schwartz-1654)

Patients with non–muscle-invasive bladder cancer (confined to the bladder mucosa or submucosa) can be managed with transurethral resection alone and adjuvant intravesical (instilled into the bladder) chemotherapy/immunotherapy.

The use of these intravesical agents is critical since patients with non–muscle-invasive bladder cancer are at risk for tumour recurrence and progression.
