The clinical effect of an electric massage chair on chemotherapy-induced nausea and vomiting in cancer patients: randomized phase II cross-over trial.

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) is a common adverse events in cancer patients and can negatively affect their quality of life (QoL). This study aimed to evaluate the clinical efficacy of an electric massage chair (EMC) for the treatment of CINV. METHODS: A randomized phase II cross-over trial was conducted on solid cancer patients who received moderate (MEC) to high emetogenic chemotherapy (HEC). The participants were randomly assigned to receive their first chemotherapy either on a standard bed (Group A) or in an EMC (Group B) during the infusion. The patients were then crossed over to the next cycle. CINV and QoL questionnaires were collected from the participants. RESULTS: A total of 59 patients completed the trial protocol and were included in the analysis, with 29 and 30 patients in Groups A and B, respectively. The mean INVR (Index of Nausea, Vomiting, and Retching) score in the 2nd day of the first cycle was higher in Group B (3.63 ± 5.35) than Group A (2.76 ± 4.78), but the difference was not statistically significant (p = 0.5367). The complete response rate showed little difference between the groups. Among the high-emetic risk subgroups, patients who received HEC (p = 0.04595), younger patients (p = 0.0108), and non-colorectal cancer patients (p = 0.0495) presented significantly lower CINV scores when EMC was applied. CONCLUSION: Overall, there was no significant difference in INVR scores between standard care and EMC. Applying EMC at the first chemotherapy infusion may help preserve QoL and reduce CINV in high-risk patients. TRIAL REGISTRATION: KCT0008200, 17/02/2023, Retrospectively registered.

Gemcitabine and oxaliplatin combination as first-line treatment for advanced pancreatic cancer: a multicenter phase II study.

PURPOSE: Gemcitabine is the only drug approved for single-agent therapy in advanced pancreatic carcinoma (APC). Gemcitabine-based combination chemotherapy has not yet shown promising results. METHODS: This multicenter phase II study enrolled previously untreated patients with locally advanced and/or metastatic pancreatic adenocarcinoma. Patients received 1,000 mg/m(2) gemcitabine, 100-min infusion, day 1 and 100 mg/m(2) oxaliplatin, 2-h infusion, day 2; q2w. The primary end point was response rate (RR). RESULTS: Thirteen study centers enrolled 48 eligible patients of which 44 were evaluable. The RR, median overall survival, and median time to progression were 18.2%, 9.4 and 5.6 months, respectively. Sixteen patients (36.4%) experienced clinical benefit. The global quality of life scores improved by 11.71. Grade 3/4 peripheral sensory neuropathy was noted (2.1%), while the most common hematologic toxicity was anemia (grade 3/4, 6.3%). CONCLUSIONS: Gemcitabine and oxaliplatin combination chemotherapy showed a promising activity in APC patients and was well tolerated.

Chromosomal aberrations in Korean nonsmall cell lung carcinomas: degenerate oligonucleotide primed polymerase chain reaction comparative genomic hybridization studies.

Chromosomal aberrations were investigated in 48 Korean nonsmall cell carcinomas of the lung (NSCLC), by degenerate oligonucleotide primed polymerase chain reaction comparative genomic hybridization. These included 16 adenocarcinomas, 27 squamous cell carcinomas (SCCs), and 5 large-cell carcinomas. The common sites of copy number increases were 3q26 approximately qter (23 cases, 48%); 8q23 approximately qter (46%); 20q13.1 (42%); 1q42 approximately qter (38%); 3q25 (38%); 21q22 (38%); and 22q13 (38%). DNA amplification was identified in 19 carcinomas (40%), and the frequent sites of amplification were 8q24 (seven cases), 3q26 (seven cases), and 3q27 (seven cases). The frequently under-represented chromosomal regions were Yq (38%), 4q25 approximately q26 (23%), and 4q31 (23%). In particular, gains of 3q26 approximately qter (74%), 15q (56%), and 19q (59%) and loss of 13q22 approximately q31 (26%) were more frequently detected in SCCs of the lung. These nonrandom aberrations can serve as starting points for the identification of potential oncogenes/tumor suppressor genes related to the tumorigenesis of Korean NSCLC.
