[Effectiveness of L-Carnitine in the Treatment of Fatigue Associated with Chemotherapy in Patients with Gastric Cancer].

AIM: Low serum carnitine levels have been reported in patients with cancer receiving chemotherapy and are considered one of the factors causing fatigue associated with chemotherapy. We evaluated the effectiveness of L-carnitine in the treatment of fatigue associated with chemotherapy in patients with gastric cancer(GC). MATERIALS AND METHODS: We performed a randomized controlled trial between December 2013 and December 2018. Untreated patients with advanced GC were included in the study; 1 patient developed an allergy after receiving the first chemotherapy and was excluded from the study. The primary endpoint was brief fatigue inventory(BFI). Patients were categorized into 2 groups: those who received L-carnitine oral supplements(group C)and those who did not receive L-carnitine oral supplements(group N). RESULTS: The serum carnitine levels were improved significantly in group C compared with group N. BFIwas more aggravated in group N than group C; however, the difference was not significant. CONCLUSION: We could not demonstrate the effectiveness of L-carnitine in the treatment of fatigue associated with chemotherapy in patients with GC.

[Pathological Complete Response of Advanced Gastric Cancer after Docetaxel and S-1 Combination Neoadjuvant Chemotherapy-A Case Report].

A 70-year-old man with left abdominal pain was referred to our hospital, and was diagnosed with type 1 advanced gastric cancer with lymph node metastasis. Neoadjuvant chemotherapy(NAC)with docetaxel and S-1 combination was administered. After 2 courses of chemotherapy, total gastrectomy with D2 lymph node dissection, splenectomy, and cholecystectomy were performed. Pathologically, viable cancer cells were not evident in the primary lesion and lymph nodes. The pathological response of NAC was judged to be Grade 3. On immunohistochemical analysis of the biopsy specimens obtained before treatment, the cancer cells were positive for class III b-tubulin and negative for TS, DPD, and ERCC1. The anti-tumor effect of S-1 may have led to the pCR.

[Clinical Experience of Nutritional Support in Patients Treated with Chemoradiotherapy for Locally Advanced Esophageal Cancer].

BACKGROUND: We investigated the efficacy of nutritional support in patients treated with chemoradiotherapy (CRT) for locally advanced esophageal cancer (LAEC). METHODS: Eleven patients treated with CRT for locally advanced esophageal squamous cell carcinoma were included. Oral intake energy expenditure (OIE) and total energy expenditure (TEE) of all patients were calculated. Oral nutrition supplementations (ONSs) were utilized as nutritional therapy for the patients with malnutrition (OIE/TEE<0.6). Enteral nutrition (EN) was used in the patients with tumor obstruction. RESULT: Two patients (18.9%) received ONS and 2 other patients received EN. Seven patients were able to take enough energy in the meal. The mean energy charge was increased from 67.9%to 84.9%. Nine patients (81.8%) completed the treatment regimen. During the CRT period, the prognostic nutritional index (PNI) and C-reactive protein level (mg/dL) were not significantly different. The body mass index decreased to 0.39 kg/m2 (p=0.039) and the mean weight loss was 1.57%. The overall response rate was 81.8%. CONCLUSION: The nutritional support in the patients treated with CRT for LAEC is effective for maintaining nutritional status. Moreover, the response rate is satisfactory.
