MDS PREP
Which of the following blood components can be expected to increase with disseminated intravascular coagulation?
1) Factor V
2) Fibrin degradation products
3) Fibrinogen
4) Plasminogen
Fibrin degradation products increase in disseminated intravascular coagulation (DIC) due to the breakdown of fibrin clots.
The following protein defects can cause hereditary spherocytosis except -
1) Ankyrin
2) Palladin
3) Glycophorin C
4) Anion transport protein
General Pathology
Answer: 3
Glycophorin C is not associated with hereditary spherocytosis; it is a sialoglycoprotein found in the red blood cell membrane, while ankyrin, palladin, and anion transport protein are involved in the structural integrity of the membrane.

The basis of adjuvant therapy in surgery followed by chemotherapy is:
1. To make chemical agents reach centre of tumour
2. Anticancer drugs are not effective against bigger tumour therefore its size is reduced by surgery
3. Debulking the tumour by surgery makes the tumour cells re-enter the cell cycle and thus become susceptible to drug therapy
4. None of the above
Pathology
Answer: 3
Debulking the tumor by surgery makes the tumor cells re-enter the cell cycle and thus become susceptible to drug therapy: This statement is the most accurate. Surgical removal of a tumor (debulking) can indeed lead to the release of tumor cells into the circulation and may also alter the tumor microenvironment. This can make residual tumor cells more susceptible to chemotherapy, as they may re-enter the cell cycle and become more actively dividing, which is when many chemotherapy agents are most effective.
