Q

What is the effect of hormone replacement therapy on risk for

endometrial CA
colorectal CA
fractures
breast CA

A

Hormone replacement therapy (HRT) with conjugated equine estrogens plus progestins increases the risk of breast cancer. Epidemiologic studies have demonstrated a rapid decrease in elevated breast cancer incidence coincident with the discontinuation of HRT. it takes 6-7 years to double breast cancer risk.

HRT increases the risk of endometrial cancer, however, administration of conjugated estrogens with progesterone abrogates the increased risk of endometrial cancer compared to estrogen alone HRT

HRT decreases the risk of bone fractures and colorectal cancer.

Q

35/F with a solitary breast mass left underwent MRM. Her histopathology report revealed invasive ductal carcinoma. Her breast panel IHCs findings revealed ER (+) PR (-) Her 2 (2+). What would be the BEST recommendation to this patient?
A. Request for repeat IHCs
B. Request for HER-2 FISH testing
C. Proceed with treatment with Hormonal therapy only
D. Proceed with treatment with Hormonal and Anti-Her2 Therapy

A

Answer: B. Request for HER-2 FISH testing

The two most important predictive factors in breast cancer are ER and HER2 expression, and they should be performed on all primary or metastatic cancer biopsy specimens. HER2 status is determined using either IHC staining for protein overexpression or fluorescent in situ hybridization (FISH) for gene amplification. IHC staining of 3+ (on a scale of 0–3+) is considered positive, whereas 0–1+ is considered negative. For cases with 2+ staining, reflex FISH analysis is recommended. FISH can either be used as the initial evaluation or for additional evaluation in IHC 2+ cases. HER2 is considered amplified if the ratio of HER2 to centromere signal on chromosome 17 is ≥2.0. FISH is unnecessary if IHC is 3+ or 0–1+, nor is there a reason for IHC testing if FISH is ≥2.0

Q

Which is TRUE about PSA testing in prostate cancer screening, diagnosis, and treatment?

A. PSA test is prostate cancer-specific
B. Digital rectal exam (DRE) may increase PSA levels
C. PSA is a useful test for screening 50 years old men for prostate cancer
D. PSA level is strongly associated with the risk and outcome of prostate cancer

A

D. PSA level is strongly associated with the risk and outcome of prostate cancer

The level of PSA in the blood is strongly associated with the risk and outcome of prostate cancer. A single PSA measured at age 60 is associated (area under the curve [AUC] of 0.90) with a lifetime risk of death from prostate cancer. Most (90%) prostate cancer deaths occur among men with PSA levels in the top quartile (>2 ng/mL), although only a minority of men with PSA >2 ng/ mL will develop lethal prostate cancer.
Option A is incorrect. PSA is produced by both nonmalignant and malignant epithelial cells and, as such, is prostate-specific, not prostate cancer–specific.

Option B is incorrect. Serum levels of PSA may increase from prostatitis, BPH, or prostate cancer. Serum levels are not significantly affected by the DRE.

Option C is incorrect. Recommendations for screening with PSA are based on shared decision-making for men between the ages of 55 and 69. PSA-based screening is a target age group for whom benefits may outweigh the harm. Outside this age range, PSA-based screening as routine is not recommended.

Q

This androgen deprivation therapy (ADT) used in managing metastatic non-castrate prostate cancer may initially cause a clinical flare of disease and is relatively contraindicated when given alone for patients with spinal cord compromise.

A

Leuprolide

GnRH agonists/antagonists, such as leuprolide acetate and goserelin acetate, initially produce a rise in LH and FSH followed by a downregulation of receptors in the pituitary gland, which effects a chemical castration. The initial rise in testosterone may result in a clinical flare of the disease, and as such, these agents are relatively contraindicated in men with significant obstructive symptoms, cancerrelated pain, or spinal cord compromise, events that do not occur with GnRH antagonists such as degarelix (Option D).

Q

Which of the following statements describes the mechanism of action of cyclophosphamide accurately?

A. Forms covalent bonds with DNA bases, leading to cross-linkage of DNA strands
B. Interferes with purine synthesis, conveying the greatest toxicity to cells in the S-phase
C. Creates double stranded breaks through which another segment of DNA duplex passes before rejoining
D. Binds to DNA through the DNA minor groove eventually leading to the disruption of the FUS-CHOP transcription action

A

Option A is the mechanism of action of alkylating agents such as cyclophosphamide (cell cycle nonspecific).

Option B is the MOA of anti-metabolites (like 5FU or capecitabine).

Option C is the MOA of Top-2 inhibitors (like doxorubicin), and

The efficacy of which drug is enhanced by leucovorin by increasing the binding of a ternary complex with thymidylate synthase?
A. Methotrexate
B. 5-fluorouracil
C. Pemetrexed
D. 6-Thioguanine

A

The action of 5-fluorouracil is synergistic with leucovorin.

Option A is incorrect because leucovorin lessens the toxicity of methotrexate to normal tissues (folate rescue, otherwise cells die a thymine-less death) .

Options C and D are also incorrect because leucovorin has no role in enhancing their efficacy.

Additional information: Pemetrexed: give folate and VitB12 to reduce hematologic toxicity 6-thioguanine: Increased toxicity with thiopurine methyltransferase deficiency

Which mechanism explains early diarrhea, occurring less than 24 hours after irinotecan administration?
A. Acetylcholinesterase inhibition by the prodrug
B. Acetylcholinesterase inhibition by the active metabolite, SN-38
C. Direct mucosal cytotoxicity from the prodrug
D. Direct mucosal cytotoxicity by the active metabolite, SN-38

A

Early diarrhea is caused by acetylcholinesterase inhibition by the prodrug, Irinotecan. In order to prevent this, patients are premedicated with atropine. Late diarrhea occurs due to direct mucosal cytotoxicity by the active metabolite, SN-38. For late diarrhea, use loperamide 4mg after the first stool then 2mg Q2 hours until 12h without stool (max 16mg/24h)

Q

Which agent may be given to patients with metastatic prostate cancer to inhibit androgen synthesis by blocking the action of CYP17A1? To counteract adverse events related to mineralocorticoid excess, this is often given together with corticosteroids.

A. Abiraterone
B. Leuprolide
C. Enzalutamide
D. Relugolix

A

Abiraterone inhibits the action of CYP17A1, thus preventing androgen biosynthesis

Leuprolide is an LHRH agonist, while Relugolix is a GNRH antagonist, preventing the release of LH and FSH, and consequently testosterone.

Enzalutamide is a second generation androgen receptor (AR) antagonist inhibiting androgen binding to AR, androgen receptor nuclear translocation, and subsequent interaction with chromosomal DNA for signaling

A patient with metastatic non-small cell lung cancer starts taking a tyrosine kinase inhibitor that targets ALK but also has anti-ROS activity. After 2 months on the treatment, he reports having suicidal ideations, altered mood and sleep. Which among the following TKIs did the patient receive?
A. Ceritinib
B. Crizotinib
C. Lorlatinib
D. Larotrectinib

A

Answer: C. Lorlatinib

Explanation: Lorlatinib targets both ALK but also has anti-ROS activity. Apart from suicidal ideations, altered mood, sleep and cognitive disturbances, this is also known to cause dyslipidemia.

Ceritinib is an ALK-inhibitor, Crizotinib inhibits both ALK and ROS but both drugs are not known to affect mood or cognition.

Larotrectinib does not have ALK or ROS activity, but rather, targets NTRK fusion mutations

Q

Which of the following cancer treatments warrants periodic monitoring for hyperglycemia?
A. Abemaciclib
B. Adagrasib
C. Alpelisib
D. Axitinib

A

Answer: C. Alpelisib

Alpelisib is a PI3K inhibitor that can cause uncontrolled hyperglycemia. It is important to monitor glucose levels and hba1c.

MTOR inhibitors (everolimus, temsorolimus) and BRAF inhibitors (regorafenib, dabrafenib) can also cause hyperglycemia

Q

Which specific genetic alteration is usually seen in etoposide-related acute myeloid leukemia?
A. Chromosome 5 or 7 deletion
B. Chromosome 11q23 translocation
C. Chromosome T(14;18) translocation
D. Chromosome T(15;17) translocation

A

B. Chromosome 11q23 translocation
This mutation in AML patients is seen after exposure to top-inhibitors (with etoposide conferring the highest risk), rarely preceded by MDS.

Chromosome 5 or 7 mutations, may be seen in patients on previous alkylating agents especially when combined with radiation ad is often preceded by myelodysplasia.

Chromosome T(14;18) translocation is the defining molecular event in follicular lymphoma.

While chromosome T(15;17) translocation is the defining molecular event in acute promyelocytic leukemia, conferring sensitivity to retinoic acid

85
Q
  1. Which of the following statements is accurate regarding the use of sputum cytology in the diagnosis of lung cancer?

A. Although lower yield than other specimen types, the yield is highest for peripherally located tumors such as adenocarcinomas
B. The specificity is about <70%, while sensitivity is 100%
C. This specimen is usually adequate for PDL1 testing and molecular testing
D. At least three sputum specimens are recommended

A

Answer: D. At least three sputum specimens are recommended Explanation:

Option D is correct because it increases specificity

Option A is incorrect because the yield is highest for centrally located tumors (not peripheral) such as small cell or squamous tumors.

Option B is incorrect: it should be specificity of 100%, while sensitivity of <70%.

Option C is incorrect since specimen or tumor cells are usually scars, preventing PDL1 testing and other molecular testing.

86
Q

Contraindications for curative resection for lung CA

A

necessitating chemoradiation or chemotherapy instead

Extrathoracic metastases, super vena cava syndrome , vocal cord paralysis, phrenic nerve paralysis, tumor within 2cm of the carina, metastases to the contralateral lung, metastases to the supraclavicular lymph nodes, metastases to contralateral mediastinal node, involvement of main pulmonary artery

87
Q

For a patient who will undergo first-line palliative chemotherapy for his metastatic lung adenocarcinoma, which chemotherapy agent will you combine with Cisplatin for improved survival?
A. Gemcitabine
B. Pemetrexed
C. Paclitaxel
D. Ramucirumab

A

Answer: B. Pemetrexed

Pemetrexed in combination with platinum chemotherapy has high activity in adenocarcinomas.

Higher thymidylate synthase is seen in squamous cancer – hence, lower responsiveness to pemetrexed. Activity of gemcitabine is not impacted by levels of thymidylate synthase – thus cisplatin/gemcitabine combination or cisplatin/paclitaxel would be used for squamous histology.

Lastly, ramucirumab in combination with docetaxel is used in the second line setting for squamous or non-sqauamous histologies– not as first line.

88
Q

Q

Which germline mutation increases one’s risk of developing gastric signet ring cell adenocarcinoma? Patients with this inherited mutation can be considered for prophylactic gastrectomy.
A. RHBDF2
B. CDH1
C. MMR
D. BRCA2

A

Answer: B. CDH1

Option B, CDH1, causes a specific subtype of gastric cancer: the diffuse or signet ring cell adenocarcinoma histology)

RHBDF2 is the germline mutation associated with tylosis palmaris et plantaris – a syndrome at high risk for esophageal SCCs.

MMR deficiency is seen in lynch syndrome (also increases one’s risk of gastric cancer).

BRCA 2 germline mutations also increases one’s risk for gastric cancer, pancreatic and prostate cancer, but more implicated in male and female breast cancers.

93
Q

Which genomic result will influence your therapeutic choice when treating metastatic gastric adenocarcinomas?
A. Epstein Barr Virus DNA by PCR
B. MMR protein deficiency
C. CDH1 mutation
D. TP53 mutation

A

B. MMR protein deficiency

Explanation: For MSI-high or dMMRP gastric cancers, Pembrolizumab is used (currently approved in second line setting)

Determining the EBV, TP53 or CDH1 status of the gastric malignancy does not influence treatment (although, these can be prognostic).

Other genomic findings that can influence treatment include: MSIH and PDL1 result (using pembrolizumab or adding nivolumab to chemotherapy), and Her2 expression or amplification (adding trastuzumab or trastuzumab deruxtecan)

94
Q

8A patient presents with stage II gastric MALT lymphoma. Upon further testing, the tumor tests positive for H.pylori on histopathology and t(11;18) by PCR. What is the most appropriate treatment for this patient?
A. Rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone (RCHOP)
B. RCHOP and radiation
C. Antibiotics for H.pylori
D. Antibiotics for H. pylori and Rituximab

A

Answer: D. Antibiotics for H. pylori and Rituximab

Option D is correct - adding radiation or rituximab is done due to lower response of t(11;18) translocation positive gastric MALT tumors to H. pylori eradication alone (making option C incorrect).

Options A and B (RCHOP+/- radiation) would be appropriate for diffuse large b cell lymphomas

95
Q

Q

Mrs. Vinson was treated a week ago with Doxorubicin and high dose Ifosfamide for her metastaic soft tissue sarcoma. She developed fever and pyuria. Absolute neutrophil count is 200/uL. Culture returned coagulase negative staphylococci. What would be the best antibiotic to give?
A. Cefipime
B. Meropenem
C. Piperacillin Tazobactam
D. Vancomycin

A

D. Vancomycin

The patient has febrile neutropenia with a culture confirming coagulase-negative Staphylococci (CoNS), which is a common cause of bloodstream infections in neutropenic patients, particularly those with indwelling catheters or devices. CoNS are often resistant to beta-lactams, and the treatment of choice in this setting is vancomycin to cover for methicillin-resistant CoNS (MRCoNS).
