Scurvy presenting in a homeless 32-year-old male: a case report.

Vitamin C deficiency, otherwise known as scurvy, is one the oldest known diseases. Although its prevalence has substantially diminished, certain populations such as smokers, alcoholics, elderly, and those with malabsorptive syndromes remain at risk. Deficiency presents with perifollicular hemorrhage, corkscrew hairs, and petechiae that can evolve into ecchymoses and purpura. Diagnosis starts with clinical suspicion and is confirmed with plasma and leukocyte ascorbic acid levels. Early suspicion is key. Treatment with vitamin C offers an excellent prognosis and avoids unnecessary workup for differential diagnoses. In our case, a 45-year-old male alcoholic with progressively worsening symptoms was found to have scurvy. Treatment was initiated with vitamin C supplementation, and he had remarkable improvement in his symptoms within weeks. This case demonstrates that scurvy is not a disease of history and must be considered in modern medicine, especially as homelessness with concomitant poor nutrition continues to increase.

Therapy of Small Cell Lung Cancer (SCLC) with a Topoisomerase-I-inhibiting Antibody-Drug Conjugate (ADC) Targeting Trop-2, Sacituzumab Govitecan.

Purpose: We evaluated a Trop-2-targeting antibody conjugated with SN-38 in metastatic small cell lung cancer (mSCLC) patients.Experimental Design: Sacituzumab govitecan was studied in patients with pretreated (median, 2; range, 1-7) mSCLC who received either 8 or 10 mg/kg i.v. on days 1 and 8 of 21-day cycles. The primary endpoints were safety and objective response rate (ORR); duration of response, progression-free survival (PFS), and overall survival (OS) were secondary endpoints.Results: Sixty percent of patients showed tumor shrinkage from baseline CTs. On an intention-to-treat basis (N = 50), the ORR was 14% (17% for the 10-mg/kg group); the median response duration, 5.7 months; the clinical benefit rate (CBR ≥4 months), 34%; median PFS, 3.7 months; and median OS, 7.5 months. There was a suggested improvement in PR, CBR, and PFS with sacituzumab govitecan in second-line patients who were sensitive to first-line therapy, but no difference between first-line chemosensitive versus chemoresistant patients in the overall population. There was a statistically significant higher OS in those patients who received prior topotecan versus no topotecan therapy in a small subgroup. Grade ≥3 adverse events included neutropenia (34%), fatigue (13%), diarrhea (9%), and anemia (6%). Trop-2 tumor staining was not required for patient selection. No antibodies to the drug conjugate or its components were detected on serial blood collections.Conclusions: Sacituzumab govitecan appears to have a safe and effective therapeutic profile in heavily pretreated mSCLC patients, including those who are chemosensitive or chemoresistant to first-line chemotherapy. Additional studies as a monotherapy or combination therapy are warranted. Clin Cancer Res; 23(19); 5711-9. ©2017 AACR.

Weekly paclitaxel and carboplatin induction chemotherapy followed by concurrent chemoradiotherapy in locally advanced squamous cell carcinoma of the head and neck.

OBJECTIVE: To perform a phase II trial evaluating dose dense induction chemotherapy for locally advanced head and neck cancer. PATIENTS AND METHODS: Thirty-five patients received 6 weekly doses of carboplatin (area under the curve=2) and paclitaxel (135 mg/m) followed by concurrent weekly paclitaxel (40 mg/m) and carboplatin (area under the curve=1) and daily radiation (66-72 Gy). RESULTS: There was 1 induction death from neutropenic sepsis and 1 sudden death during chemoradiotherapy. The overall response rate with induction was 79%. With >40 months of follow-up, the 36-month overall survival was 67% and squamous cell carcinoma of the head and neck survival 84%. Patients undergoing biopsy of the primary tumor site after the therapies had 17/18 (94%) pathologic complete response rate. The locoregional relapse rate was 40% (24 mo 28%) and distant relapse rate was 8% with only 1 distant site. CONCLUSIONS: Therapy was active but patients must be carefully selected and monitored. Compared with the historical controls, dose dense and intense induction chemotherapy decreased distant failure rate without compromising the locoregional control.
