Background: This systemic analysis was conducted to evaluate the efficacy and safety of pemetrexed based chemotherapy in treating patients with metastatic gastric cancer (MGC) as a salvage chemotherapy. Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for patients with gastric cancer were identified by using a predefined search strategy. Pooled response rates (RRs) of treatment were calculated. Results: In pemetrexed based regimens, 4 clinical studies including 171 patients with advanced gastric cancer were considered eligible for inclusion. Systemic analysis suggested that, in all patients, pooled RR was 25.1% (43/171) in pemetrexed based regimens. Major adverse effects were neutropenia, anorexia, fatigue, and anemia. No treatment related death occurred in pemetrexed based treatment. Conclusion: This systemic analysis suggests that pemetrexed based regimens are associated with mild activity with good tolerability in treating patients with MGC.

Increasing scientific evidence suggests that ribonucleotide reductase M1 (RRM1) may be a powerful predictor of survival in patients with pancreatic cancer treated with adjuvant gemcitabine-based chemotherapy after operative resection, but many existing studies have yielded inconclusive results. This meta-analysis aimed to assess the prognostic role of RRM1 in predicting survival in patients with pancreatic cancer treated with gemcitabine. An extensive literature search for relevant studies was conducted on PubMed, Embase, Web of Science, Cochrane Library, and CBM databases from their inception through May 1st, 2013. This meta-analysis was performed using the STATA 12.0 software and crude hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated. Eight clinical studies were included in this meta-analysis with a total of 665 pancreatic cancer patients treated with adjuvant gemcitabine-based chemotherapy, including 373 patients in the high RRM1 expression group and 292 patients in the low RRM1 expression group. Our meta-analysis revealed that high RRM1 expression was associated with improved overall survival (OS) of pancreatic cancer patients (HR=1.56, 95%CI=0.95-2.17, P<0.001). High RRM1 expression also was linked to longer disease-free survival (DFS) than low RRM1 expression (HR=1.37, 95%CI=0.25-2.48, P=0.016). In conclusion, our meta-analysis suggests that high RRM1 expression may be associated with improved OS and DFS of pancreatic cancer patients treated with adjuvant gemcitabine-based chemotherapy. Detection of RRM1 expression may be a promising biomarker for gemcitabine response and prognosis in pancreatic cancer patients.

Objective: To show a decrease in tumor recurrence and improvement in quality of life in patients with recurrent cervical cancer. Method: A 58-year-old female patient diagnosed with recurrent cervical cancer in February 2021 was treated for 14 months with integrative cancer treatment (ICT) to decrease the tumor size and improve chemotherapy-induced peripheral neuropathy (CIPN) and nausea. The patient underwent chemotherapy or concomitant chemoradiation therapy (CCRT) with ICT. Radiologic outcomes were assessed by abdomen & pelvis computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography-computed tomography (PET-CT) based on the Response Evaluation Criteria in Solid Tumors (RECIST) protocol. Clinical outcomes were assessed by the National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), Eastern Cooperative Oncology Group (ECOG), and a numeric rating scale (NRS). Result: During the 14 months of treatment, the size and metabolic activity of the recurrent tumor decreased and underwent partial remission based on RECIST. The NRS scores for CIPN and nausea were improved, and the ECOG score improved from grade 2 to 1. No serious side effects of grade 3 or higher were noted on the NCI-CTCAE test. Conclusion: This case suggests that ICT may have a synergetic effect with chemotherapy or radiotherapy for recurrent cervical cancer.

Objective: To demonstrate an improvement in metastatic cancer pain and a decrease in tumor size in a patient with non-small cell lung cancer. Method: A 53-year-old female patient diagnosed with metastatic non-small cell lung cancer in August 2022 underwent integrative cancer treatment (ICT) for two months to decrease the tumor size and improve back pain from bone metastasis. The patient underwent chemotherapy with ICT. Radiologic outcomes were assessed by chest, abdomen, and pelvis computed tomography based on the Response Evaluation Criteria in Solid Tumors (RECIST) protocol. Clinical outcomes were assessed using National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), Eastern Cooperative Oncology Group (ECOG), and a numeric rating scale (NRS). Result: During the two months of treatment, the NRS scores for back pain were improved, and the ECOG score improved from grade 2 to 1. The size and metabolic activity of the primary lung tumor decreased and underwent partial remission based on RECIST. No serious side effects of grade 3 or higher were noted on the NCI-CTCAE test. Conclusion: This case suggests that ICT may have a therapeutic effect for cancer pain and a synergetic effect with chemotherapy for metastatic non-small cell lung cancer.

Gastric cancer (GC) is one of the deadliest malignancies in the world. Currently, clinical treatment decisions are mostly made based on the extent of the tumor and its anatomy, such as tumor-node-metastasis staging. Recent advances in genome-wide molecular technology have enabled delineation of the molecular characteristics of GC. Based on this, efforts have been made to classify GC into molecular subtypes with distinct prognosis and therapeutic response. Simplified algorithms based on protein and RNA expressions have been proposed to reproduce the GC classification in the clinical field. Furthermore, a recent study established a single patient classifier (SPC) predicting the prognosis and chemotherapy response of resectable GC patients based on a 4-gene real-time polymerase chain reaction assay. GC patient stratification according to SPC will enable personalized therapeutic strategies in adjuvant settings. At the same time, patient-derived xenografts and patient-derived organoids are now emerging as novel preclinical models for the treatment of GC. These models recapitulate the complex features of the primary tumor, which is expected to facilitate both drug development and clinical therapeutic decision making. An integrated approach applying molecular patient stratification and patient-derived models in the clinical realm is considered a turning point in precision medicine in GC.

Cisplatin is the most effective and widely used chemotherapeutic agent for many types of cancer. Unfortunately, its clinical use is limited by its adverse effects, notably bone marrow suppression leading to abnormal hematopoiesis. We previously revealed that neuropeptide Y (NPY) is responsible for the maintenance of hematopoietic stem cell (HSC) function by protecting the sympathetic nervous system (SNS) fibers survival from chemotherapy-induced bone marrow impairment. Here, we show the NPY-mediated protective effect against bone marrow dysfunction due to cisplatin in an ovarian cancer mouse model. During chemotherapy, NPY mitigates reduction in HSC abundance and destruction of SNS fibers in the bone marrow without blocking the anticancer efficacy of cisplatin, and it results in the restoration of blood cells and amelioration of sensory neuropathy. Therefore, these results suggest that NPY can be used as a potentially effective agent to improve bone marrow dysfunction during cisplatin-based cancer therapy.

Hand-foot syndrome (HFS) frequently occurs after receiving chemotherapy, such as sorafenib, in patients with hepatocellular carcinoma (HCC), and this impairs quality of life (QOL). The prevalence of HFS due to sorafenib is 10-28%. The effective methods to treat HFS are not established aside from temporary discontinuation of chemotherapy agents and drug dosage adjustment because the mechanism of HFS has not been elucidated. According to a previous study, modified Dohongsamul-tang was effective in the treatment of patients with HFS and improved patients' QOL. Based on these results, we administered the soaking method with modified Dohongsamul-tang to a 50-year-old male patient with HCC complaining of HFS due to sorafenib. After two weeks, the symptoms of HFS were improved despite taking sorafenib. We suggest that modified Dohongsamul-tang is a novel method for treating HFS.

Purpose: This study aimed to explore changes in symptom distress and functional status in gynecologic cancer patients during the entire treatment cycles of chemotherapy. Methods: A prospective and longitudinal study with repeated measures was designed. Symptom Distress Scale and Karnofsky Performance Status Index were included in a daily log developed for self-administration. A total of 39 patients with a mean age of 48.4 years participated. Results: The levels of symptom distress and functional status changed significantly over the six cycles. Symptom distress kept increasing until its peak at the fourth cycle, while the functional status scored lowest at the first cycle, then it improved as the cycle repeated. In each cycle, symptom distress was marked higher during the first 6 days accompanying poor functional status. However, both changes did not recover completely until the end of each cycle. Conclusion: Nursing assessment and intervention need to be provided based on these changing patterns to help cancer patients cope and adjust successfully during the long treatment period. Further studies are needed to examine the impact of the major symptoms on psychological responses, quality of life, and outcomes of the cancer treatments.
