Axillary Lymph Node Dissection
A) Indications: Clinical or radiological evidence of involvement of axillary nodes Microscopically positive sentinel node(s) due to metastasis from primary malignant tumor In sentinel node negative: 98 % accurate in predicting that the other nodes are negative In sentinel node positive: possibility of microscopic disease in any of the remaining lymph nodes is 15–30…

Principles of Chemotherapy
Master the knowledge of clinically relevant cell cycle to understand the principles of chemotherapy. Tumors that are highly responsive to chemotherapeutic agents (e.g., testicular cancer, lymphomas) tend to have a very rapid doubling time compared to tumors that are less responsive to chemotherapy (e.g., pancreatic and prostate cancers). The tumor doubling time of metastases…

Aspirin and Clopidegrol : Perioperative Guidelines
The average lifespan of platelets is 7 to 10 days. Aspirin and Clopidegrol inhibits platelets for around 21 days. Hence, when these agents are stopped 7 days before the surgery, it allows 33% regeneration of platelets. Stents and coronary lesions act as unstable plaque until they are completely covered by…
