Effect of immunotherapy-infusion time of day on survival of patients with advanced cancers: a study-level meta-analysis. ESMO Open 2024; 9:102220. [PMID: 38232612 PMCID: PMC10937202 DOI: 10.1016/j.esmoop.2023.102220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 12/09/2023] [Accepted: 12/15/2023] [Indexed: 01/19/2024] Open
Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) have become the standard of care for numerous malignancies. Emerging evidence suggests that the time of day (ToD) of ICI administration could impact the outcomes of patients with cancer. The consistency of ToD effects on ICI efficacy awaits initial evaluation. MATERIALS AND METHODS This meta-analysis integrates progression-free survival (PFS) and overall survival (OS) data from studies with a defined 'cut-off' ToD. Hazard ratios (HRs) [95% confidence interval (CI)] of an earlier progression or death according to 'early' or 'late' ToD of ICIs were collected from each report and pooled. RESULTS Thirteen studies involved 1663 patients (Eastern Cooperative Oncology Group performance status 0-1, 83%; males/females, 67%/33%) with non-small-cell lung cancer (47%), renal cell carcinoma (24%), melanoma (20%), urothelial cancer (5%), or esophageal carcinoma (4%). Most patients received anti-programmed cell death protein 1 or anti-programmed death-ligand 1 (98%), and a small proportion also received anti-cytotoxic T-lymphocyte-associated protein 4 (anti-CTLA-4) (18%). ToD cut-offs were 13:00 or 14:00 (i.e. ICI median infusion time), for six studies, and 16:00 or 16:30 (i.e. reported threshold for weaker vaccination responses) for seven studies. Pooled analyses revealed that the early ToD groups had longer OS (HR 0.50, 95% CI 0.42-0.58; P < 0.00001) and PFS (HR 0.51, 95% CI 0.42-0.61; P < 0.00001) compared with the late ToD groups. CONCLUSIONS Patients with selected metastatic cancers seemed to largely benefit from early ToD ICI infusions, which is consistent with circadian mechanisms in immune-cell functions and trafficking. Prospective randomized trials are needed to establish recommendations for optimal circadian timing of ICI-based cancer therapies.

Abstract
Everolimus (EV), a rapamycin analogue mTOR inhibitor, is used in the clinic to treat Estrogen positive (ER+) breast cancer in order to avoid the resistance to hormonotherapy. Here, we investigated whether EV efficacy varied according to administration timing by using the ER+ breast cancer cell line MCF-7 as model system. Our results showed that instead of apoptosis, EV induced a G0/G1 phase blockage of MCF-7 cells. Following serum shock, MCF-7 cells displayed a statistically significant 24h rhythm of mammalian target of Rapamycin (mTOR) activity, but perturbed circadian clock genes oscillations. Interestingly, the different delivery schedule of EV presented different efficacy in G0/G1 phase blockage in serum shocked MCF-7 cells. Moreover, serum shock induced also a circadian-like oscillation in expression or activity of several important G1 phase progression proteins, such as Cyclin D1 and phosphorylated Retinoblastoma protein (RB). Inhibition mTOR activity by EV reduced Cyclin D1 and Cyclin D3 protein level as well as RB phosphorylation level. Taken together, the results indicated that serum shock synchronization induced a circadian oscillation in mTOR activity in MCF-7 cells, which rhythmically regulated the synthesis or phosphorylation of key G1 progression proteins, such as Cyclin D1 and phosphorylated RB, ultimately resulting in different G0/G1 blockage efficiency according to different EV administration timing.

Abstract
The circadian timing system determines the optimal timing and waveform of drug tolerability, yet treatment itself can alter this system. Gemcitabine is an antimetabolite agent that is active against lung and pancreatic cancers. Tolerability for this drug is best following dosing at ZT 11 in mice. The authors investigated the effects of gemcitabine on the circadian rhythms in body temperature and rest activity as physiological markers of the circadian timing system. Healthy unrestrained B6D2F1 mice implanted with radiotelemetry transmitters were kept in LD 12:12 prior to receiving a single intravenous dose of gemcitabine (200, 400, or 600 mg/kg) at ZT 11 or 23. Gemcitabine (400 mg/kg) transiently suppressed the body temperature rhythm in 50% of the mice dosed at ZT 23, as compared to none of the mice treated at ZT 11 within the 2 days following drug dosing (Fisher 's exact test p = 0.04). The rest-activity circadian rhythm was suppressed in 40% (ZT 11) and 50% (ZT 23) of the mice, respectively. In the mice with persistent circadian rhythms, gemcitabine delivery at ZT 23 resulted in more prominent decreases and slower recovery of circadian mesor and amplitude of both rhythms as compared to mice treated at ZT 11. Gemcitabine also induced a transient internal desynchronization between temperature and activity rhythms following dosing at ZT 23 but not at ZT 11. The delivery of a single therapeutic dose of gemcitabine near its time of least toxicity produced least alterations in circadian physiological outputs, a finding that suggests that the extent of circadian disruption contributes to toxicokinetic processes.

Abstract
BACKGROUND Molecular circadian clocks can modify cancer chemotherapy effects, with a possible moderation according to sex differences. We investigated whether sex determine the optimal delivery schedule of chemotherapy for metastatic colorectal cancer. PATIENTS AND METHODS A meta-analysis was performed using individual data from three international Phase III trials comparing 5-fluorouracil, leucovorin and oxaliplatin administered in chronomodulated (chronoFLO) or conventional (CONV) infusions. The data from 345 females and 497 males were updated at 9 years. The main end point was survival. RESULTS Overall survival was improved in males on chronoFLO when compared with CONV (P = 0.009), with respective median values of 20.8 (95% CL, 18.7 to 22.9) and 17.5 months (16.1 to 18.8). Conversely, median survival was 16.6 months (13.9 to 19.3) on chronoFLO and 18.4 months (16.6 to 20.2) on CONV in females (P = 0.012). The sex versus schedule interaction was a strong predictive factor of optimal treatment schedule, with a hazard ratio of 1.59 (1.30 to 1.75) for overall survival (P = 0.002) in multivariate analysis. CONCLUSIONS Males lived significantly longer on chronomodulated chemotherapy rather than on conventional chemotherapy. The current chronoFLO schedule deserves prospective assessment as a safe and more effective first-line treatment option than conventional delivery for male patients.

Abstract
BACKGROUND The impact of bevacizumab on functional recovery and histology of the liver was evaluated in patients undergoing hepatic resection for colorectal liver metastases (CLM) following bevacizumab treatment. METHODS Consecutive patients who had resection of CLM between July 2005 and July 2009 following preoperative chemotherapy were identified retrospectively from a prospectively collected database. Patients who had received bevacizumab before the last chemotherapy line were excluded. Postoperative liver function and histology were compared between patients with and without bevacizumab treatment. Recorded parameters included serum prothrombin time, total bilirubin concentration, and levels of aspartate and alanine aminotransferase and γ-glutamyltransferase. RESULTS Of 208 patients identified, 67 had received last-line bevacizumab, 44 were excluded and 97 had not received bevacizumab. Most patients in the bevacizumab group (66 per cent) received a single line of chemotherapy. Bevacizumab was most often combined with 5-flurouracil/leucovorin and irinotecan (68 per cent). The median number of bevacizumab cycles was 8·6 (range 1-34). Bevacizumab administration was stopped a median of 8 (range 3-19) weeks before surgery. There were no deaths. Postoperative morbidity occurred in 43 and 36 per cent of patients in the bevacizumab and no-bevacizumab groups respectively (P = 0·353). The mean(s.d.) degree of tumour necrosis was significantly higher in the bevacizumab group (55(27) versus 32(29) per cent; P = 0·001). Complete pathological response rates were comparable (3 versus 8 per cent; P = 0·307). Postoperative changes in functional parameters and objective signs of hepatic toxicity were similar in both groups. CONCLUSION Preoperative administration of bevacizumab does not seem to affect functional recovery of the liver after resection of CLM. Tumour necrosis is increased following bevacizumab treatment.

Abstract
Cetuximab was approved using a weekly schedule, alone or in combination with chemotherapy (CT). However, many CT regimens in metastatic colorectal cancer (CRC) are delivered every 2 weeks (q2wks). Preliminary data suggested that a simplified schedule using cetuximab q2wks, 500 mg/m² would be equivalent to the standard weekly administration. Medical data of all patients with advanced CRC who received cetuximab q2wks were retrospectively collected and checked for consistency by an independent monitor in 4 European centers. Ninety-one patients were treated between 2005 and 2007 when the K-RAS mutational status of tumors was not determined routinely. They received a median of 4 (0-5) previous drugs, including previous weekly cetuximab in 38.5% of patients. Cetuximab q2wks was associated with an irinotecan-based regimen in 85.7% of patients. The median number of cetuximab administrations was 6 (1-23). Skin toxicity was observed in 68.2% of evaluable patients (grade 3 in 15%). Only one grade 1 allergy was reported. In the 84 patients beyond first-line therapy, response rate was 29.3%. The median progression-free survival was 3.0 months (range 2.2-3.8), and median overall survival was 9.0 months (range 6.2-11.8). Cetuximab q2wks appears safe and effective in heavily pretreated patients and convenient in combination with q2wks CT schedules.

Abstract
Irinotecan hydrochloride (CPT-11) can display severe toxicities in individual cancer patients. CPT-11 is bio-activated through CES, detoxified through UGT1A1 and inhibits TOP1. CPT-11 toxicity and UGT1A1, CES2 and TOP1 mRNAs and UGT1A1 protein were determined in male and female C57BL/6, B6D2F1 and B6CBAF1, as potential models for tailoring CPT-11 delivery. CPT-11 was administered intravenously (40-90 mg/kg/day for 4 days at 7h after light onset). The relations between dose and lethal toxicity or body weight loss were steep and similar in C57BL/6 (lethality, p=0.001; weight loss, p=0.002) and B6D2F1 (p=0.01; p=0.03, respectively), but weak in B6CBAF1. Females displayed less toxicity than males (p<0.001). Mean mRNA expression of UGT1A1 was highest in B6CBAF1 (p=0.039) and in females (p<0.001). Both CES2 and TOP1 varied according to strain and gender (p<0.001). The three gene expression data explained the most severe toxicity of CPT-11 in male B6D2F1, but displayed inconsistent relations with toxicity in the other groups. Mean UGT1A1 protein expression was highest in males as compared to females, and so by approximately 8-fold in C57BL/6 as compared to B6D2F1 (p<0.0001). Genetic background and gender significantly altered the molecular prediction of irinotecan toxicity by UGT1A1, CES2 and TOP1 mRNA expressions.

Abstract
4097 Background: Regenerative nodular hyperplasia (RNH) represents the worst evolutive stage of vascular lesions induced by prolonged chemotherapy on the liver. Its incidence and impact on the outcome of resection for colorectal liver metastases (CLM) are however unknown. We evaluated the effect of RNH on postoperative morbidity and assessed its evolution in time at repeat hepatectomy. Methods: All patients that underwent hepatectomy for CLM between January 1990 and November 2006 after 1 line of chemotherapy of more than 6 cycles were included. Detailed histopathologic analysis of the nontumoral liver was performed at first and repeat hepatectomies according to a standard format. Results: Of 146 included patients, 24 (16%) received 5- fluorouracil (5-FU) and leucovorin (LV) alone, 92 (63%) had 5-FU, LV and oxaliplatin, 18 (12%) had 5-FU, LV and irinotecan, and 12 (8%) were treated by 5-FU, LV, oxaliplatin and irinotecan. Overall, RNH occurred in 22 of 146 patients (15%). Patients treated by oxaliplatin more often had RNH compared to oxaliplatin-naïve patients (22% vs 4%) (P=0.003). The presence of RNH was associated with increased postoperative hepatic morbidity (23% vs 11%) (P=0.05). None of the RNH patients died within 60 days postoperatively. A preoperative gamma-glutamyltransferase level >80 U/L and a total bilirubin level >15 μmol/L were independent predictive factors of RNH at first hepatectomy. Two of 22 patients with RNH underwent repeat hepatectomy. RNH disappeared at second hepatectomy in both patients following prolonged treatment with irinotecan. Conclusions: Patients with CLM that receive prolonged courses of preoperative oxaliplatin have an increased risk of RNH and associated postoperative hepatic morbidity. Upfront treatment with short courses of highly effective regimens may therefore be most appropriate. In addition, the continuation of oxaliplatin should be discouraged in case of RNH to avoid its negative effects on further surgery. No significant financial relationships to disclose.

Abstract
4093 Background: The influence of bevacizumab on postoperative morbidity in patients with colorectal liver metastases (CLM) submitted to hepatectomy has been evaluated. However, in spite of a potential inhibition of liver regeneration, its impact on postoperative liver function recovery remains unknown. Methods: From July 2005 to December 2007, we evaluated 37 patients treated with bevacizumab prior to hepatectomy. Postoperative evolution of liver function variables was compared with that of 70 bevacizumab-naïve patients. Recorded parameters included prothrombin time, serum aspartate and alanine aminotransferase levels, and serum gamma-glutamyltransferase and total bilirubin levels. Results: Most patients of the bevacizumab group received 1 line of chemotherapy (62% vs 54% in the control group) (P=0.43). Bevacizumab was combined to 5-fluorouracil (5-FU), leucovorin (LV) and irinotecan or 5-FU, LV and oxaliplatin in the last preoperative line, in 57% and 30% of cases, respectively. Patients received a mean total number of 10.4+5.7 and 11.1+6.2 cycles of preoperative chemotherapy in the bevacizumab and control group (P=0.56). The median number of administered bevacizumab cycles was 6 (range: 3–25). Bevacizumab administration was stopped at a median of 7.9 weeks before surgery (range: 3.6–18.0). Major hepatectomies were performed in 41% and 36% of bevacizumab and control patients, respectively (P=0.62). Baseline liver function tests as well as postoperative liver function recovery were similar between patients treated with or without bevacizumab (Table). Postoperative morbidity occurred in 35% of bevacizumab patients and in 43% of control patients (P=0.44). Conclusions: Preoperative bevacizumab treatment has no impact on short-term liver function recovery after hepatic resection for CLM and has no deleterious effect on the incidence of postoperative morbidity.

Abstract
2566 Background: We previously showed that a) irinotecan (I) could be combined with chronoFLO in MMC patients; b) least toxic times (LTT) for combined I and oxaliplatin respectively correspond to the middle of the rest-phase and the middle of acivity-phase in tumor-bearing mice; c) chrono I showed adequate activity in a randomized phase II trial; and d) MMC resistance can be partly overcome with chronoIFL. Methods: The objective was to identify the LTT for I characterized by a minimal dose reduction/delay among the first 3 courses (c). Assuming that the toxic effect of I had a 24-h periodicity patients were randomized in 6 groups with I peak delivery (180 mg/m2, 6-h sinusoidal infusion on day 1) at 1:00, 5:00, 9:00 am, 1:00, 5:00, or 9:00 pm. . All the groups received also chronoFLO on days 2–5, q 3 weeks (F 700 mg/m2/d & L 150 mg/m2/d; from 22:15 to 9:45 with peak delivery at 4:00 , O 20 mg/m2/d from 10:15 to 21:45, with peak delivery at 16:00). Based on a logistic regression model, a 15% reduction in toxic events in the first 3 c, 186 patients were considered necessary to estimate the LTT with a 95% CI (calculated by bootsrap) of less than 6 h. Results: 197 of 199 randomized MMC patients were considered for tolerability and safety with median age 61 years (30–81), sex (M 68% - F 32%) and PS (0/1/2 73/23/4%); therapy was 1st line in 77 patients and 2nd line in 23%. Thithy-one percent of severe protocol violations occurred, 16% of pump malfunctions (>10% dose delivery deviation). Median number of c was 6 (1–18). There were 3 toxic deaths. The observed LTT for I tolerability was 3:15 am (95 CI: 3:40–1:50 pm, NS). Grade 3–4 diarrhea ranged from 34 to 51.6% with LTT at 1:53 pm (4:29 -2:53 am, not significant, NS); neutropenia from 9 to 25% with LTT at 3:26 pm (10:50 - 4:55 am, NS). Age was a negative prognostic factor for diarrhea (p =0.01). Conclusion: This trial failed to show a statistically significant LTT for this combination in MCC patients. The safety profile of I combined with ChronoIFLO was acceptable, with diarrhea and neutropenia within previously reported range. No significant financial relationships to disclose.

Abstract
The relation between circadian physiology (rest-activity and body temperature) and the growth of a grafted tumor (Glasgow osteosarcoma-GOS) was investigated in the mice with mutation of clock gene (ClockDelta19(-)) or gene controlled by the clock (Vpac(-/-)). Circadian rhythms in temperature and activity were stable, with an approximately 24-h period in all the mice synchronized by the alternation of 12 h of light and 12 h of darkness (LD 12:12). Following exposure to constant darkness (DD), both rhythms persisted in ClockDelta19(-), yet with a lengthening of the period by 4.5 h compared to wild type. In DD, the amplitude increased by 45.9% for the temperature rhythm (p<0.001) and by 17.4% for the activity one (p=0.08) as compared to LD 12:12 in ClockDelta19(-). The improvement of circadian coordination and/or the lengthening of the circadian period observed in ClockDelta19(-) kept in DD was associated with a moderate slowing down of tumor growth. Although the exposure to DD ablated the activity and temperature rhythms in Vpac(-/-), no modification in tumor growth was observed as compared to wide type or Vpac(-/-) in LD 12:12. Major alternations of circadian physiology can result from interactions between photoperiodic environment and mutation of clock gene or gene controlled by the clock. In these conditions, we have shown that the alternation of the circadian phenotype does not seem to constitute an essential determinant of the growth of a grafted tumor.

Abstract
Currently, the circadian timing system of cancer patients can be estimated with wrist actimetry, which provides numerical data on the continuous activity of patients. The method of processing of these data, which we implemented, aims at answering the following questions: is the circadian timing system stable before chemotherapy, is this system extensively modified by chemotherapy, are there structural modifications or a decrease in activity amplitude produced by chemotherapy and how does the circadian activity rhythm recover? Here, we determine a circadian model function using a wavelet transform prior to chemotherapy delivery. Then we measure the correlation between this model function and the evolution of the circadian rhythm of activity over the whole observation span during and after chemotherapy. The application of this method to the record of activity rhythms in cancer patients highlights the characteristics and the recovery pattern of chemotherapy-induced alterations of the circadian timing system.

Abstract
The authors reviewed experimental and clinical data emphasizing the importance for host to keep a reference circadian rythmicity. This assessment seems true both in the cancerogenesis phase, as well in the active phase of tumoural disease.

Abstract
Circadian clock genes have been identified in humans but information regarding their expression has remained very limited. However from a basic point as well as in a diagnostic and therapeutic perspective, it is important to evaluate molecular clock gene expression. Peripheral blood mononuclear cells represent an ideal material to investigate non-invasively the human clock at the molecular level. Several studies including ours reported rhythmic expression of clock genes in these cells, with significant intersubject variability of expression. In addition, our results reveal the existence of different chronotypes of clock gene expression patterns and suggest specific regulatory mechanisms in these human cells as compared to other peripheral tissues.

Abstract
The circadian clock orchestrates cellular functions over 24 hours, including cell divisions, a process that results from the cell cycle. The circadian clock and cell cycle interact at the level of genes, proteins, and biochemical signals. The disruption or the reinforcement of the host circadian timing system, respectively, accelerates or slows down cancer growth through modifications of host and tumor circadian clocks. Thus, cancer cells not only display mutations of cell cycle genes but also exhibit severe defects in clock gene expression levels or 24-hour patterns, which can in turn favor abnormal proliferation. Most of the experimental research actively ongoing in this field has been driven by the original demonstration that cancer patients with poor circadian rhythms had poor quality of life and poor survival outcome independently of known prognostic factors. Further basic research on the gender dependencies in circadian properties is now warranted, because a large clinical trial has revealed that gender can largely affect the survival outcome of cancer patients on chronotherapeutic delivery. Mathematical models further show that the therapeutic index of chemotherapeutic drugs can be optimized through distinct delivery profiles, depending on the initial host/tumor status and variability in circadian entrainment and/or cell cycle length. Clinical trials and systems-biology approaches in cancer chronotherapeutics raise novel issues to be addressed experimentally in the field of biological clocks. The challenge ahead is to therapeutically harness the circadian timing system to concurrently improve quality of life and down-regulate malignant growth.
