ABSTRACT

Background: Hyperprogressive disease is an unexpected response pattern observed in immune checkpoint therapy and associated with poor prognosis. The rechallenge of programmed cell death 1/programmed cell death ligand 1 (PD-1/PD-L1) inhibitors can be a treatment option in non-small cell lung cancer (NSCLC) patients who once responded to them. Here, we reported the hyperprogressive phenomenon after PD-1/PD-L1 rechallenge in a patient with NSCLC. Case Description: This case report described a patient with recurrent large cell lung cancer undergoing hyperprogressive disease with pleural and pericardial dissemination shortly after the pembrolizumab rechallenge, although he had a favorable response to the initial pembrolizumab treatment. A lower ratio of CD8+ T cells to Foxp3+ regulatory T cells was distributed in the cell blocks of pleural and pericardial effusion which were taken after hyperprogressive disease, compared to the resected tumor microenvironment. Neutrophil-to-lymphocyte ratio (NLR) was lower in peripheral blood when the disease was controlled and it rose when the disease progressed. Notably, NLR increased dramatically when hyperprogression occurred. Conclusions: For the first time, we reported that a patient who showed a favorable response to initial anti-PD-1 treatment underwent hyperprogressive disease when rechallenging the same immunotherapy. The increased Foxp3+ regulatory T cells in the tumor microenvironment and the longitudinal change of NLRs in peripheral blood were suggested to be associated with hyperprogressive disease.

ABSTRACT

BACKGROUND The aim of this study was to compare nutrition-related adverse events and clinical outcomes of ifosfamide, carboplatin, and etoposide regimen (ICE therapy) and ranimustine, carboplatin, etoposide, and cyclophosphamide regimen (MCEC therapy) instituted as pretreatment for autologous peripheral blood stem cell transplantation. MATERIAL AND METHODS We enrolled patients who underwent autologous peripheral blood stem cell transplantation between 2007 and 2012. Outcomes were compared between ICE therapy (n=14) and MCEC therapy (n=14) in relation to nutrient balance, engraftment day, and length of hospital stay. In both groups, we compared the timing of nutrition-related adverse events with oral caloric intake, analyzed the correlation between length of hospital stay and duration of parenteral nutrition, and investigated the association between oral caloric intake and the proportion of parenteral nutrition energy in total calorie supply. Five-year survival was compared between the groups. RESULTS Compared with the MCEC group, the ICE group showed significant improvement in oral caloric intake, length of hospital stay, and timing of nutrition-related adverse events and oral calorie intake, but a delay in engraftment. Both groups showed a correlation between duration of parenteral nutrition and length of hospital stay (P=0.0001) and between oral caloric intake (P=0.0017) and parenteral nutrition energy sufficiency rate (r=-0.73, P=0.003; r=-0.76, P=0.002). Five-year survival was not significantly different between the groups (P=0.1355). CONCLUSIONS Our findings suggest that compared with MCEC therapy, ICE therapy improves nutrition-related adverse events and reduces hospital stay, conserving medical resources, with no significant improvement in long-term survival. The nutritional pathway may serve as a tool for objective evaluation of pretreatment for autologous peripheral blood stem cell transplantation.

ABSTRACT

BACKGROUND: Cancer cachexia in elderly patients may substantially impact physical function and medical dependency. The aim of this study was to estimate the impact of cachexia on activity of daily living (ADL), length of hospital stay, and inpatient medical costs among elderly patients with advanced non-small-cell lung cancer (NSCLC) receiving chemotherapy. METHODS: Thirty patients aged ≥70 years with advanced NSCLC (stage III-IV) scheduled to receive first-line chemotherapy were prospectively enrolled between January 2013 and November 2014. ADL was assessed using the Barthel index. The disability-free survival time (DFS) was calculated as the time between the date of study entry and the date of onset of a disabling event, which was defined as a 10-point decrease in the Barthel index from that at baseline. The mean cumulative function of the length of hospital stay and inpatient medical costs (¥, Japanese yen) was calculated. RESULTS: The study patients comprised 11 women and 19 men, with a median age of 74 (range, 70-82) years. Cachexia was diagnosed in 19 (63%) patients. Cachectic patients had a shorter DFS (7.5 vs. 17.1 months, p < 0.05). During the first year from study entry, cachectic patients had longer cumulative lengths of hospital stay (80.7 vs. 38.5 days/person, p < 0.05), more frequent unplanned hospital visits or hospitalizations (4.2 vs. 1.7 times/person, p < 0.05), and higher inpatient medical costs (¥3.5 vs. ¥2.1 million/person, p < 0.05) than non-cachectic patients. CONCLUSIONS: Elderly NSCLC patients with cachexia showed higher risks for disability, prolonged hospitalizations, and higher inpatient medical costs while receiving chemotherapy than patients without cachexia. Our results might indicate that there is a potential need for an early intervention to minimize progression to or development of cachexia, improve functional prognosis, and reduce healthcare resource burden in this population.

ABSTRACT

BACKGROUND: Elderly patient with advanced cancer is one of the most vulnerable populations. Skeletal muscle depletion during chemotherapy may have substantial impact on their physical function. However, there is little information about a direct relationship between quantity of muscle and physical function. We sought to explore the quantitative association between skeletal muscle depletion, and muscle strength and walking capacity in elderly patients with advanced non-small cell lung cancer (NSCLC). METHODS: Thirty patients aged ≥70 years with advanced NSCLC (stage III-IV) scheduled to initiate first-line chemotherapy were prospectively enrolled between January 2013 and November 2014. Lumbar skeletal muscle index (LSMI, cm2/m2), incremental shuttle walking distance (ISWD, m), and hand-grip strength (HGS, kg) were assessed at baseline, and 6 ± 2 weeks (T2) and 12 ± 4 weeks (T3) after study enrollment. Associations were analyzed using linear regression. RESULTS: Altogether, 11 women and 19 men with a median age of 74 (range, 70-82) years were included in the study; 24 received cytotoxic chemotherapy and 6, gefitinib. Mean ± standard deviation of LSMI, ISWD and HGS were 41.2 ± 7.8 cm2/m2, 326.0 ± 127.9 m, and 29.3 ± 8.5 kg, respectively. LSMI and ISWD significantly declined from baseline to T2 and T3. HGS significantly declined from baseline to T2 and T3 only in men. Change in LSMI was significantly associated with change in HGS (ß = 0.3 ± 0.1, p = 0.0127) and ISWD (ß = 8.8 ± 2.4, p = 0.0005). CONCLUSIONS: Skeletal muscle depletion accompanied with physical functional decline started in the early phase of the chemotherapy in elderly patients with advanced NSCLC. Our results suggest that there may be a need for early supportive care in these patients to prevent functional decline during chemotherapy.
