RESUMEN
Aims: In this study, we focused on the fat ratio within psoas muscle (FRPM) and sought to clarify the impact of FRPM on overall survival (OS) in stage IV gastric cancer (GC) patients undergoing systemic chemotherapy (n = 79, median age = 69 years, 59 males). Methods: The median FRPM was 1.67 %. Forty patients with FRPM ≥1.67 % were defined as the FRPM-high group, and the remaining 39 patients was defined as the FRPM-low group. The median PMI in male and female patients was 4.35 cm2/m2 and 2.88 cm2/m2. Thirty male patients with PMI ≥4.35 cm2/m2 and 10 female patients with PMI ≥2.88 cm2/m2 was defined as the PMI-high group, and the remaining 39 patients was defined as the PMI-low group. Results: The 1-, 2- and 3- year cumulative OS rate for all cases was 70.8%, 24.3% and 14.6%. The proportion of ECOG-PS 2 or 3 in patients with FRPM-high and FRPM-low was 17.5% (7/40) and 2.6% (1/39). The 1-, 2- and 3- year cumulative OS rate in patients with FRPM-high and FRPM-low was 67.3%, 14.3% and 7.6% in the FRPM-high group and 74.8%, 40.5% and 32.4% in the FRPM-low group (P = 0.0341). The 1-, 2- and 3- year cumulative OS rate in patients with PMI-high and PMI-low was 86.7%, 40.4% and 30.0% in the PMI-high group and 55.8%, 12.8% and 6.4% in the PMI-low group (P < 0.0001). In the multivariate analysis of factors associated with OS, PMI (P = 0.0047) and FRPM (P = 0.0019) were independent predictors for the OS. Conclusion: Higher FRPM can be associated with decreased physical activity, and not only skeletal muscle mass but also skeletal muscle function can be an essential prognostic factor in stage IV GC patients undergoing systemic chemotherapy.
RESUMEN
BACKGROUND/AIM: To prospectively evaluate the efficacy and safety of the BNT162b2 vaccine in solid cancer patients undergoing systemic chemotherapy (n=63). PATIENTS AND METHODS: COVID-19 anti-spike protein antibody levels were measured before the first BNT162b2 vaccination, just before the second BNT162b2 vaccination, one month after the second BNT162b2 vaccination, and 3 months after the second BNT162b2 vaccination. Anti-spike protein antibody seropositivity was set at ≥0.8 U/ml. RESULTS: Colorectal cancer was the most commonly observed primary disease (36.5%). ECOG-PS 0 was observed in the majority (52.4%) of patients. The overall response rate and the median (range) anti-spike protein antibody levels in the whole cohort at 3 months after the second BNT162b2 vaccination were 98.4% (62/63) and 206 (0.4-3,813) U/ml. None of the patients required postponement or discontinuation of systemic chemotherapy because of an adverse reaction. CONCLUSION: The BNT162b vaccine in solid cancer patients undergoing systemic chemotherapy is effective and safe.

We sought to elucidate factors contributing to the grip strength (GS) decline in patients with gastrointestinal diseases (Ga-Ds, n = 602, 379 males, median age = 72 years). The GS decline in males and females was defined as <28 kg and <18 kg, respectively, following the current Asian guidelines. The median GS (male) was 28.8 kg, and GS decline (male) was found in 169 patients (44.6%). The median GS (female) was 17.5 kg, and GS decline (female) was found in 122 patients (54.7%). Advanced cancer was identified in 145 patients (24.1%). In terms of the univariate analysis of parameters of the GS decline, age (p < 0.0001), gender (p = 0.0181), body mass index (BMI, p = 0.0002), ECOG-PS (p < 0.0001), SARC-F score (p < 0.0001), hemoglobin value (p < 0.0001), total lymphocyte count (p < 0.0001), serum albumin value (p < 0.0001), C reactive protein (CRP) value (p < 0.0001), and estimated glomerular filtration rate were statistically significant. In terms of the multivariate analysis, age (p < 0.0001), BMI (p = 0.0223), hemoglobin value (p = 0.0186), serum albumin value (p = 0.0284), the SARC-F score (p = 0.0003), and CRP value (p < 0.0001) were independent parameters. In conclusion, the GS decline in patients with Ga-Ds is closely associated with not only the primary factor (i.e., aging) but also secondary factors such as inflammatory factors and nutritional factors.
RESUMEN
BACKGROUND: Fosaprepitant, an NK1 receptor antagonist, inhibits and induces cytochrome P450 3A4 (CYP3A4) as its substrate. Contrarily dexamethasone is metabolized by CYP3A4. Therefore, in combination therapy wherein both agents interact with each other, it is recommended that the dexamethasone dose be reduced in the first two days. Thus far, there are only a few studies on the optimum dose of dexamethasone after day 3. Thus, we aimed to determine the pharmacokinetics of dexamethasone on day3 when administered together with fosaprepitant and investigate the dose-dependent differences in its antiemetic effect in patients with cancer. METHODS: Twelve patients with esophageal, stomach, or lung cancer received primary highly emetogenic chemotherapy (HEC). We intravenously administered 9.9 mg and 6.6 mg of dexamethasone on days 1 and 2, respectively, and 6.6 mg or 13.2 mg on day 3 together with the administration of 150 mg fosaprepitant and 0.75 mg palonosetron. We assessed the pharmacokinetics of dexamethasone on day 3 by dose and examined the dose-dependent antiemetic effect. RESULTS: No differences were observed in the time-to-maximum concentration and blood half-life of dexamethasone between patient groups that received dexamethasone at doses of 6.6 mg and 13.2 mg. In contrast, the area under the blood concentration-time curve and the maximum concentration of dexamethasone correlated with its dose. Moreover, the blood dexamethasone concentration on day 3 increased by twofold after the administration of a higher dose than after a lower dose. The severity of nausea in the delayed phase significantly decreased in a dose-dependent manner. CONCLUSION: Administration of a higher dexamethasone dose on day 3 improved the antiemetic effect of the combined regimen in patients with cancer who underwent HEC.

AIM: Gastric cancer patients are normally treated with oral fluoropyrimidine and cisplatin or oxaliplatin; however, treating patients who also have a gastrointestinal obstruction is often difficult because of their poor oral intake. Instead, a modified (m)FOLFOX-6 regimen is administered, even to patients with gastrointestinal obstructions. The aim of this study was to assess the efficacy of mFOLFOX-6 for gastric cancer patients with a gastrointestinal obstruction. METHODS: Patients with a poor oral intake because of a gastrointestinal obstruction who received mFOLFOX-6 as systemic chemotherapy were retrospectively analyzed. Poor oral intake was defined as receiving a daily intravenous drip infusion due to a gastrointestinal obstruction. RESULTS: Eighteen patients received mFOLFOX-6; the median progression-free survival was 6.8 months (95% confidence interval [CI], 1.9-9.7), the median overall survival was 8.0 months (95% CI, 2.8-20.8) and the median time to treatment failure was 2.2 months (95% CI, 1.2-5.7). An improved oral intake was observed in 13 of the 18 treated patients, with 12 of these continuing treatment as outpatients. CONCLUSIONS: A mFOLFOX-6 treatment regimen seems promising for gastric cancer patients who have a gastrointestinal obstruction.

OBJECTIVE: Recent guidelines have adopted an incidence of febrile neutropenia (FN) threshold of 20% for the use of prophylactic granulocyte colony-stimulating factor (G-CSF). In a Japanese phase II study of a combination chemotherapy regimen consisting of oxaliplatin, irinotecan, fluorouracil and leucovorin (FOLFIRINOX) for Japanese patients with advanced pancreatic cancer, the incidence of FN and severe neutropenia were 24.7% and 77.8%, respectively, without G-CSF prophylaxis. The aim of this retrospective study was to investigate the incidence of FN or severe neutropenia induced by full-dose FOLFIRINOX administration with G-CSF prophylaxis during the first cycle of treatment. METHODS: Patients with advanced pancreatic cancer who received FOLFIRINOX with G-CSF prophylaxis during the first cycle of treatment from January 2014 to August 2014 were investigated and the frequency of adverse events during the first cycle was measured. RESULTS: Among seven patients who received FOLFIRINOX, six patients met the eligibility criteria. The patient characteristics were as follows: median age (range), 57 (50-66); men/women, 3/3; performance status 0/1, 2/4. Grade 3/4 hematological adverse events were as follows: leukopenia in 33% of the patients, neutropenia in 33% of the patients, thrombocytopenia in 33% of the patients and FN in 17% of the patients. One patient was heterozygous for the UGT1A1*6 and UGT1A1*28 polymorphisms and experienced FN. Grade3/4 non-hematological adverse events were as follows: anorexia in 33% of the cases and nausea in 50% of the cases. CONCLUSION: Although the present study was retrospective and small, the simultaneous administration of G-CSF might be effective for the prevention of severe neutropenia and FN in patients treated with FOLFIRINOX.

A 72-year-old previously healthy man visited our hospital with complaints of hoarseness and dysphagia. Computed tomography showed wall thickening of the thoracic esophagus; invasion to the left main bronchus, aorta, and right supraclavicular lymph nodes (LNs); right recurrent nerve LNs; and cardiac LN swelling. Esophagogastroduodenoscopy revealed an elevated tumor in the middle thoracic esophagus, which was similar to a submucosal tumor and had a longitudinal ulcer at its center. Pathologicexamination showed a tumor with a high N/C ratio, and immunohistochemical staining showed the tumor was CD56 and NSE positive, with a Ki-67 index >80%. We diagnosed esophageal neuroendocrine carcinoma (NEC), cT4N3M0, Stage IVa. We started chemotherapy with irinotecan and cisplatin (IP therapy) according to a regimen for small-cell lung cancer. After 3 courses of chemotherapy, the primary lesion and the LN swelling had almost disappeared. Esophageal NEC is relatively rare disease, so there are no standard established treatments. We report a case of esophageal NEC for which IP therapy was effective with the relevant literature cited.

BACKGROUND/AIM: Combination chemotherapies of oxaliplatin or irinotecan with fluoropyrimidine and molecular target drug were reported to be active in several clinical studies and so regarded as a first-line standard therapy for unresectable or metastatic colorectal cancer. However, the incidence of adverse events is not so low. We investigated the efficacy and safety of chemotherapy combined bevacizumab with fluoropyrimidine as a first-line treatment for frail patients. METHODS: Twenty-six patients with unresectable or metastatic colorectal cancer who were treated with first-line chemotherapy combined bevacizumab with S-1 or 5FU/LV (modified Roswell Park Memorial Institute regimen) at our hospital between October 2007 and December 2010 were retrospectively investigated. RESULTS: The median age was 72 years (range 66-84). Performance status was 0, 1 and 2 in 8, 17 and 1 patient, respectively. The primary lesion was located in the colon in 14 patients and in the rectum in 12. Twenty patients were with resection of the primary lesion and 6 were without, 8 were with postoperative adjuvant chemotherapy and 18 were without. The number of metastasized organs was 1, 2 and 3 in 17, 9 and 0 patients, respectively. The liver, lung, lymph node and peritoneum were metastasized in 9, 9, 11 and 5 patients, respectively. The KRAS gene was wild in 11, mutated in 7 and unknown in 8 patients. Bevacizumab with S-1 was used in 17 patients and bevacizumab with 5FU/LV was used in 9. Response and disease control rates were 50 and 100%, respectively. The median duration of progression-free survival was 9.1 months and the median time to treatment failure was 9.0 months. The incidences of all grades of neutropenia and hypertension were 31%, those of grade 3 or severer were 12%, and those of other adverse events were low. Grade 3 cerebral hemorrhage, grade 4 pulmonary embolism and grade 5 febrile neutropenia each occurred in 1 patient. CONCLUSION: The first-line chemotherapy combined bevacizumab with fluoropyrimidine for frail patients with unresectable or metastatic colorectal cancer in Japan was comparable to the safety and efficacy of combination therapy reported previously in Western countries.

Since elderly people have decreased renal function along with increased risks for complications of cardiac disorders such as hypertension and decreased physical strength, compared to in younger people, drug therapy for them is associated more with concern about drug-related toxicity. Therefore, dose reduction or discontinuation of drug administration is sometimes considered during earlier stages of therapy. On the other hand, there are some reports suggesting that as long as proper organ function is maintained, the elderly can be treated in the same way as younger people. However, given limited information and depending on the therapeutic goal of each patient, it should be carefully considered whether the same medicinal strategy used for younger patients is appropriate for treating elderly patients or not.
