Association between diabetes mellitus and reduced efficacy of pembrolizumab in non-small cell lung cancer.

BACKGROUND: Diabetes mellitus (DM) is a highly prevalent chronic metabolic disorder. Although DM has been associated with immune dysfunction, the effect of DM on the efficacy of immunotherapy is unknown. This study aimed to evaluate the impact of DM on the efficacy of pembrolizumab in metastatic non-small cell lung cancer (NSCLC). METHODS: The authors reviewed the medical records of consecutive metastatic NSCLC patients treated with first-line pembrolizumab either alone or in combination with chemotherapy at a single tertiary center. For validation, a computerized data from Maccabi Healthcare Services, a 2.5-million-member state health service was used. RESULTS: Of the 203 eligible patients, 51 (25%) had DM. Patients with DM had a significantly shorter median progression-free survival (PFS) (5.9 vs. 7.1 months, p = .004) and overall survival (OS) (12 vs. 21 months, p = .006). The shorter OS in diabetic patients was more pronounced when pembrolizumab was given alone (12 vs. 27 months, p = .03) than when combined with chemotherapy (14.3 vs. 19.4 months, p = .06). Multivariate analysis confirmed DM as an independent risk factor for shorter PFS (hazard ratio [HR], 1.67; 95% confidence interval [CI], 1.11-2.50, p = .01) and OS (HR, 1.73; 95% CI, 1.09-2.76, p = .02). In a validation cohort of 452 metastatic NSCLC patients, the time on pembrolizumab treatment was shorter in diabetic patients (p = .025), with only 19.6% of patients remaining on treatment at 12 months compared to 31.7% of the nondiabetic patients. CONCLUSIONS: This study suggests immunotherapy is less beneficial in diabetic NSCLC patients. More work is needed to verify our findings and explore similar effects in other cancer entities.

ALK Inhibitors or Chemotherapy for Third Line in ALK-positive NSCLC? Real-world Data.

OBJECTIVES: ALK inhibitors (ALKi) are the standard-of-care treatment for metastatic ALK-rearranged non-small cell lung cancer (NSCLC) in the first- and second-line setting. We conducted a real-world multi-institutional analysis, aiming to compare the efficacy of third-line ALKi versus chemotherapy in these patients. METHODS: Consecutive ALK-positive metastatic NSCLC patients treated with at least one ALKi were identified in the working databases of 7 Israeli oncology centers (the full cohort). Demographic and clinical data were collected. Patients receiving any systemic treatment beyond 2 ALKi comprised the third-line cohort, whether a third ALKi (group A) or chemotherapy (group B). Groups A and B were compared in terms of overall survival (OS) and time-to-next-treatment line (TNT). RESULTS: At a median follow-up of 41 months (95% confidence interval [CI]: 32-55), 80 (47.1%) have died. Median OS (mOS) in the full cohort (n = 170) was 52 months (95% CI: 32-65). Number of ALKi (hazard ratio [HR] 0.765; 95% CI: 0.61-0.95; P = .024) and age (HR 1.02, 95% CI: 1.01-1.04, P = .009) significantly associated with OS in the full cohort. The third-line cohort included 40 patients, of which 27 were treated with third ALKi (group A) and 13 treated with chemotherapy (group B). mOS from third-line initiation was 27 months in group A (95% CI: 13-NR) and 13 months for group B (95% CI: 3-NR); the difference was not significant (NS; P = .12). Chemotherapy as first line (HR 0.17, 95% CI: 0.05-0.52, P = .002) and a higher number of ALKi (HR 0.38, 95% CI: 0.20-0.86, P = .011) associated significantly with longer OS of the third-line cohort. TNT was 10 months for group A (95% CI: 5-19) and 3 months for group B (95% CI: 0-NR); the difference was NS (P = .079). CONCLUSION: We report mature real-world data of more than 4-year mOS in ALK-positive patients. The number of ALKi given was associated with a better outcome. OS and TNT demonstrated a statistically nonsignificant trend for a better outcome in patients receiving a third-line ALKi.

Severe Postoperative Complications are Associated with Impaired Survival in Primary but not in Recurrent Retroperitoneal Sarcoma.

BACKGROUND: Retroperitoneal sarcoma (RPS) surgery entails multivisceral resection, which may cause postoperative complications. We assessed the effects of complications on survival to identify their predisposing factors in primary (PRPS) and recurrent (RRPS) RPS. METHODS: We retrospectively analyzed our institutional database. Severe postoperative complications (SC) were defined as Clavien-Dindo classification ≥ 3. Predisposing factors for complications were investigated, as was their effect on long-term outcomes. RESULTS: In total, 154 RPS resections (78 PRPS and 76 RRPS) performed between January 2008 and December 2018 were included. Neoadjuvant chemotherapy and multifocal tumors were more common in RRPS than PRPS (34.2% vs. 11.3%, P = 0.001 and 42.1% vs. 10.3%, P < 0.001, respectively). Although surgical extent in RRPS was limited compared with PRPS (weighted organ score 1 vs. 2, P = 0.01; transfusion requirement 23.6% vs. 35.8%, P = 0.04), SC and mortality rates were comparable. SC rates were 30.1% and 35.5% for PRPS and RRPS, respectively. NACT rate tended to be higher in PRPS patients with SC (20.8% vs. 7.4%, P = 0.09), whereas weighted organ score and transfusion requirement were increased in RRPS patients with SC (2 vs. 1, P = 0.01; 40.7% vs. 14.3%, P = 0.009, respectively). PRPS patients with SC had decreased overall survival (35 months, 95% confidence interval [CI] 12.2-57.7) compared with those without SC (90 months, 95% CI 71.4-108.5, P = 0.01). CONCLUSIONS: Postoperative complications are associated with impaired outcomes in PRPS but not in RRPS. The negative effects of complications on outcomes should be factored to perioperative management.

Cardio-toxicity among patients with sarcoma: a cardio-oncology registry.

BACKGROUND: Chemotherapy induced cardio-toxicity has been recognized as a serious side effect since the first introduction to anthracyclines (ANT). Cardio-toxicity among patients with breast cancer is well studied but the impact on patients with sarcoma is limited, even though they are exposed to higher ANT doses. The commonly used term for cardio-toxicity is cancer therapeutics related cardiac dysfunction (CTRCD), defined as a left ventricular ejection fraction (LVEF) reduction of > 10%, to a value below 53%. The aim of our study was to estimate the prevalence of CTRCD in patients diagnosed with sarcoma and to describe the baseline risk factors and echocardiography parameters among that population. METHODS: Data were collected as part of the Israel Cardio-Oncology Registry (ICOR), enrolling all patients evaluated in the cardio-oncology clinic at our institution. The registry was approved by the local ethics committee and is registered in clinicaltrials.gov (Identifier: NCT02818517). All sarcoma patients were enrolled and divided into two groups - CTRCD group vs. non-CTRCD group. RESULTS: Among 43 consecutive patients, 6 (14%) developed CTRCD. Baseline cardiac risk factors were more frequent among the non-CTRCD group. Elevated left ventricular end systolic diameter and reduced Global Longitudinal Strain were observed among the CTRCD group. During follow-up, 2 (33%) patients died in the CTRCD group vs. 3 (8.1%) patients in the non-CTRCD group. CONCLUSIONS: CTRCD is an important concern among patients with sarcoma, regardless of baseline risk factors. Echocardiography parameters may provide an early diagnosis of cardio-toxicity.

Innate inflammatory markers for predicting survival in retroperitoneal sarcoma.

INTRODUCTION: Existing prognostic tools for retroperitoneal sarcomas (RPS) utilize parameters that can be accurately determined only postoperatively. This study evaluated the application of the neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) levels for predicting prognosis in primary RPS. MATERIALS AND METHODS: We retrospectively analyzed our database of patients with primary RPS operated between 2008 and 2018. The NLR was calculated from preoperative blood tests and its association with outcomes was determined. RESULTS: The NLR values of 78 suitable patients were analyzed. Patients were classified in the NLR-high group if the NLR was ≥2.1. High-grade tumors were more common in the NLR-high group (71.6% vs 48%, P = .02). NLR-high patients had impaired overall survival (OS) and progression-free survival (PFS) compared to NLR-low patients (median OS not reached vs 74 months 95% confidence interval [CI]: 21.6-126.4, P = .03; median PFS not reached vs 48 months 95% CI: 6.5-98.6, P = .06, respectively). Multivariate analysis showed statistical significance only for PFS but not for OS (hazard ratio [HR] = 4.1, P = .03; HR = 2.3, P = .3). Patients with low CRP levels had improved OS and PFS. CONCLUSIONS: The NLR may serve as a preoperative, easily derived marker for prognosis in RPS. Serum biomarkers may prove useful in these large and spatially heterogeneous tumors.

Rising Incidence of Lung Cancer in Arab Females, Jewish Females, and Arab Males from 1990 to 2014 in Israel.

BACKGROUND: Lung cancer is the most common cause of cancer-related death. OBJECTIVES: To identify changing patterns of lung cancer and its histologic subtypes among different population groups in Israel over a 25 year period. METHODS: Primary lung cancers, all types and all stages, diagnosed during 1990-2014 were recorded in the Israel National Cancer Registry database. Demographic information was retrieved from the National Population Register. Age-standardized rates for the different subgroups were calculated for each year. Joinpoint software was used to analyze trends in incidence. RESULTS: We identified 42,672 lung cancer cases. The most common histology was adenocarcinoma (34%), followed by squamous cell carcinoma (19%), large cell/not-otherwise-specified (19%), other histologies (15%), and small cell lung cancer (11%). The adenocarcinoma incidence rose from 25.7% to 48.2% during the examined period. Large cell/not-otherwise-specified incidence peaked around 2005-2006 and declined after. Lung cancer incidence increased significantly for the population overall and specifically in Arab females, followed by Jewish females and by Arab males. Adenocarcinoma and small cell lung cancer increased in Jewish females and in Arab males. A younger age of diagnosis was seen in Arab compared to Jewish patients. CONCLUSIONS: Jewish females and Arab males and females living in Israel demonstrated a constant increase in lung cancer incidence, mostly in adenocarcinoma and small cell lung cancer incidence. In addition, a younger age of diagnosis in Arabs was noted. Smoking reduction interventions and screening should be implemented in those populations.

Trabectedin for Advanced Soft Tissue Sarcoma: Ten Year Real-Life Perspective.

BACKGROUND: Trabectedin is a marine-derived chemotherapy, which has received U.S. Food and Drug Administration approval for use in anthracycline-resistant advanced soft tissue sarcoma (STS), especially liposarcoma and leiomyosarcoma (L-sarcomas). OBJECTIVES: To describe our 10 year real-life experience with trabectedin regarding safety and efficacy in a cohort of 86 patients. METHODS: In our study cohort, 46.51% were diagnosed with liposarcoma and 43.02% with leiomyosarcoma. A total of 703 cycles of trabectedin were given, with a median of five cycles per patient (range 1-59). Median overall survival was 13.5 months for the whole cohort, 11 months for liposarcoma patients (range 1-63), and 15 months for leiomyosarcoma patients (range 1-35). RESULTS: There was no statistically significant difference in progression free survival when stratified according to previous treatment lines given. Trabectedin exhibited a favorable safety profile, with only 22% requiring dose reductions. Grade 3 and higher toxicity was noted in 25% of the patients, mostly due to myelosuppression. There were no treatment-related deaths. CONCLUSIONS: Trabectedin is a safe and effective drug for treating advanced STS. Our results reflect real-life data with patients receiving the drug as a third and even fourth line of treatment, or with a suboptimal performance status, yet achieving impressive clinical benefit rates and survival.

Treatment patterns and clinical outcomes with pazopanib in patients with advanced soft tissue sarcomas in a compassionate use setting: results of the SPIRE study.

BACKGROUND: A named patient program (NPP) was designed to provide patients with advanced soft-tissue sarcoma (aSTS) access to pazopanib, a multitargeted tyrosine kinase inhibitor. The SPIRE study was a retrospective chart review of participating patients. PATIENTS AND METHODS: Eligibility criteria for the NPP and SPIRE mirrored those of the pivotal phase-III study, PALETTE, which compared pazopanib with placebo in patients ≥18 years with aSTS and whose disease had progressed during or following prior chemotherapy or were otherwise unsuitable for chemotherapy. Outcomes of interest included treatment patterns, treatment duration, relative dose intensity, progression-free survival (PFS), overall survival (OS), clinical benefit rate, adverse events (AEs) and reasons for treatment discontinuation. RESULTS: A total of 211 patients were enrolled (median age 56 years; 60% female). Most patients received pazopanib in second- and third-line therapy (28.0% and 28.4%, respectively), followed by fourth line (19.0%) and ≥ fifth line (18.5%). The median duration of pazopanib treatment was 3.1 months (95% CI: 2.8-3.8), with a mean daily dose of 715 mg equating to 92% of recommended dose. Median OS was 11.1 months and clinical benefit rate was 46%. There was evidence of some clinical benefit across most histological subtypes. At study end, 40% of patients were alive and of these, 18% remained on pazopanib. Thirteen percent (13%) of patients discontinued pazopanib due to AEs. CONCLUSIONS: The SPIRE study demonstrated activity of pazopanib in heavily pretreated aSTS patients in a compassionate use setting. No new safety concerns were noted. Reassuringly, the relative dose intensity of pazopanib was 92%.

Visceral Fat Content Correlates with Retroperitoneal Soft Tissue Sarcoma (STS) Local Recurrence and Survival.

BACKGROUND: Our aim was to evaluate the association between visceral fat content with soft tissue sarcoma (STS) local recurrence and survival. METHODS: One hundred and one computed tomography imaging studies of primary STS patients who had complete macroscopic resection at our institution between 2002 and 2012 were reviewed, and retroperitoneal and circumferential fat contents were measured. Correlations between imaging findings and clinical data were analyzed. RESULTS: Fifty-seven STS tumors (56.4%) were retroperitoneal; of them, 65% were high grade, median size was 15 cm (range 3-49), and the most common histological subtype was high grade liposarcoma (31.6%). Median follow-up length for the entire cohort was 64 months (range 6-95). High visceral fat (VF) content≥15 versus <15 mm was identified as a risk factor for retroperitoneal STS local recurrence; 65.1 versus 26.7%, respectively (p=0.04); VF content did not correlate with distant metastasis. Median overall survival (OS) length of patients with VF≥15 versus <15 mm was 57 months (range 2-144) versus not reached, respectively (p=0.007). Multivariable analysis identified VF≥15 mm as an independent risk factor for decreased OS (HR: 4.2, 95% CI 1.07-16.67). In contrast, circumferential fat content did not correlate with retroperitoneal STS patient outcomes. CONCLUSION: High VF content is an independent adverse prognosticator associated with significantly higher rates of retroperitoneal STS local recurrence and decreased patients survival. Local tumor biology may be affected by the presence of adipose cells. Further clinical and molecular research is needed to establish this premise.

EGFR mutation testing practice in advanced non-small cell lung cancer.

PURPOSE: Testing tumor samples for the presence of a mutation in the epithelial growth factor receptor (EGFR) gene is recommended for advanced non-squamous non-small cell lung cancer (NSCLC) patients. We aimed to collect data about common practice among Medical Oncologists treating lung cancer patients, regarding EGFR mutation testing in advanced NSCLC patients. METHODS: An internet-based survey was conducted among members of the Israeli Society for Clinical Oncology and Radiotherapy involved in the treatment of lung cancer patients. RESULTS: 24 Oncologists participated in the survey. The participants encompass the Oncologists treating most of the lung cancer patients in Israel. 79% of them use EGFR testing routinely for all advanced NSCLC patients. Opinions were split regarding the preferable biopsy site for EGFR testing material. 60% of participants recommend waiting for EGFR test results prior to initiation of first-line therapy. CONCLUSIONS: EGFR testing is requested in Israel routinely by most treating Oncologists for all advanced NSCLC patients, regardless of histology. In most cases, systemic treatment is deferred until the results of this test are received.

The prognostic value of beta-1 blockers in patients with non-small-cell lung carcinoma treated with pembrolizumab.

BACKGROUND: Immune checkpoint inhibitors (ICIs) such as pembrolizumab have revolutionized the treatment of metastatic non-small cell lung cancer (mNSCLC). Beta-adrenergic activation contributes to cancer initiation and progression. While non-selective beta-blocker were found to improve the efficacy of ICIs therapy, the role of beta-1 (ß1)-selective -blocker (ß1B) in lung cancer patients is unknown. OBJECTIVE: To evaluate the effect of ß1B on overall survival (OS) and progression-free survival (PFS) in patients diagnosed with mNSCLC and treated with pembrolizumab. METHODS: We performed a retrospective analysis of patients diagnosed with mNSCLC and treated with first-line pembrolizumab at our center. RESULTS: Of 200 eligible patients, 53 (27%) were pretreated with ß1B. Patients in the ß1B cohort were older (73 ± 8 vs. 67 ± 10 years, p < 0.001) with a higher prevalence of cardiac risk factors and cardiovascular (CV) diseases including ischemic heart disease (32% vs. 16%, p = 0.010), heart failure (9% vs. 3%, p = 0.043) and atrial fibrillation (23% vs. 3%, p < 0.001). Compared to the non-ß1B group, patient pretreated with ß1B had a significant shorter median OS (12 vs. 24 months, p = 0.004) and PFS (6 vs. 8 months, p < 0.001). In a multivariate analysis, including all CV risk factors and diseases, the use of baseline ß1B was a strong and independent predictor for accelerated disease progression (HR 1.92, 95%CI 1.32-2.79, p < 0.001) and shorter OS (HR 1.8, 95%, CI 1.18-2.75, p = 0.007). CONCLUSIONS: The use of baseline ß1B showed a strong and independent association for shorter OS and PFS in patients diagnosed with mNSCLC and treated with pembrolizumab.

The effect of long-standing lymphopenia after radiation therapy on survival in rectal cancer.

BACKGROUND: Lymphopenia and high neutrophil-to-lymphocyte ratio are known negative prognostic factors in rectal cancer. Until recently, however, lymphopenia was regarded as a minor sequela following radiation therapy (RT). The immune system's influence on rectal cancer treatment outcomes led us to evaluate the impact of lymphopenia at various time points, before, during, and following radiotherapy. We hypothesized that chronic lymphopenia following radiotherapy might negatively influence the survival of patients, and pre-treatment lymphopenia may be predictive of poor outcomes. METHODS: This retrospective study involved 110 patients treated for rectal cancer between 2015 and 2019. The oncological outcomes are defined as alive without disease (AWOD), alive with disease (AWD), and death. These outcome probabilities tested against variables of lymphopenia before RT, during RT, and at several post-RT follow-up time points. RESULTS: At the end of the study, 69 patients were AWOD (63 %), 13 were AWD (12 %) and 28 had died (25 %). Treatment results were assessed with according level of lymphocytes measured one year following RT: 35 out of 39 patients (89.7 %) with normal values were AWOD. In 65 patients with sustained lymphopenia, 52 % were AWOD, 18.5 % AWD and 29 % died. A similar difference was found at all time-points up to 2 years following RT (p < 0.004). The results of our study shows that pre-existing lymphopenia (prior to RT) is associated with a 3 times greater chance of death compared to patients with normal lymphocyte levels prior to RT. The PFS significantly affected by lymphopenia at all time-points after RT. An NLR of more than 4 was associated with a 3-time higher risk of recurrence than lower NLR scores (p = 0.0054). CONCLUSION: Our results support the relevance of lymphopenia and NLR in the prognosis of rectal cancer. We believe this is the first study showing a negative correlation between sustained lymphopenia and OS following RT.

Artificial intelligence (AI) molecular analysis tool assists in rapid treatment decision in lung cancer: a case report.

Leptomeningeal involvement among non-small cell lung cancer (NSCLC) patients is an aggressive form of disease that requires quick and efficient treatment. In this case report, we describe a woman in her 40s with a presenting symptom of headache that ultimately was diagnosed as leptomeningeal spread from NSCLC adenocarcinoma. We identified EGFR mutation in less than 48 hours from the biopsy using imagene-artificial intelligence's real-time algorithmic solution on the pathological diagnostic slide.

The use of medical cannabis concomitantly with immune checkpoint inhibitors in non-small cell lung cancer: A sigh of relief?

BACKGROUND: The use of medical cannabis has rapidly increased among cancer patients worldwide. Cannabis is often administered concomitantly with cancer medications, including immune checkpoint inhibitors (ICIs). As the cannabinoid receptors are abundantly expressed and modulate immune cells, it has been hypothesised that cannabis may attenuate the activity of ICIs. We aimed to assess the effect of cannabis on ICIs' efficiency in patients having non-small cell lung cancer (NSCLC). METHOD: The murine model of CT26 tumour-bearing mice treated with an anti-PD-1 antibody and Δ9-tetrahydrocannabinol (THC) was used to evaluate the interaction between THC and ICIs in vivo. Correlation between use of medical cannabis and clinical outcome was evaluated in a cohort of 201 consecutive metastatic NSCLC patients treated with monotherapy pembrolizumab as a first-line treatment. RESULTS: Median overall survival (OS) of the mice receiving a control vehicle, THC, anti-PD-1 antibody or their combination was 21, 24, 31 and 54 days, respectively (p < 0.05 for the combination treatment compared to a control vehicle), indicating that THC did not reduce the efficacy of anti-PD-1 therapy. Of 201 NSCLC patients treated with first-line monotherapy pembrolizumab for metastatic disease, 102 (50.7%) patients received licence for cannabis within the first month of treatment. Cannabis-treated patients were younger compared to the cannabis naïve patients (median age 68 versus 74, p = 0.003), with female predominance (62, 60.8% versus 34, 34.3%, p = 0.002) and with more prevailing brain metastasis (15.7% versus 5%, p = 0.013). Similar distribution of histology, smoking status, ECOG (Eastern Cooperative Oncology Group) and programmed death-ligand 1 expression was noted between the groups. Liver metastases were marginally significant (19.6% versus 10.1%, p = 0.058). The most common indication for cannabis was pain (71%) followed by loss of appetite (34.3%). Time to tumour progression was similar for cannabis-naive and cannabis-treated patients (6.1 versus 5.6 months, respectively, 95% confidence interval, 0.82 to 1.38, p = 0.386), while OS was numerically higher in the cannabis-naive group (54.9 versus 23.6 months) but did not reach statistical significance (95% confidence interval 0.99 to 2.51, p = 0.08). In multivariate analyses, we did not identify cannabis use as an independent predictor factor for mortality. CONCLUSIONS: Preclinical and clinical data suggest no deleterious effect of cannabis on the activity of pembrolizumab as first-line monotherapy for advanced NSCLC. The differences in OS can most likely be attributed to higher disease burden and more symptomatic disease in the cannabis-treated group. These data provide reassurance regarding the absence of a deleterious effect of cannabis in this clinical setting.

The predictive value of high sensitivity troponin measurements in patients treated with immune checkpoint inhibitors.

BACKGROUND: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of cancer; however, at the potential cost of serious adverse events including cardiac injury. OBJECTIVE: To assess the baseline and longitudinal changes in high sensitivity-Troponin (hs-Tn) in patients treated with pembrolizumab as a potential predictor for the development of major adverse cardiac events (MACE) and survival. METHODS: We performed a retrospective analysis of cancer patients treated with pembrolizumab at our center. All participants had baseline measurements of hs-TnI prior to initiation of pembrolizumab (T1), with half of the patients performing follow-up measurements at their second encounter for therapy introduction (T2). We first evaluated the prevalence of abnormally elevated serum hs-TnI (> 50 nanogram per liter) at T1 and T2. We then evaluated the predictive value of abnormal levels at T1 or T2 in relation to the development of MACE (composite outcomes of myocarditis, acute coronary syndrome, heart failure, venous thromboembolism, cardiovascular hospitalization and cardiovascular mortality) and all-cause mortality. RESULTS: Among 135 patients, the mean age was 72 years, predominantly male (61%). Abnormally elevated hs-TnI at T1 was observed in 7 (5%) patients and emerged as a significant independent predictor for MACE (HR 8.1, 95% CI 1.67-37.4, p = 0.009) and all-cause mortality (HR 5.37, 95% CI 2.1-13.57, p < 0.001). Abnormally elevated hs-TnI at T2 was observed in 8 (11%) patients and emerged as a significant independent predictor for MACE (HR 10.49, 95% CI 1.68-65.5, p = 0.009), but not for mortality (p = 0.200). CONCLUSIONS: Abnormally elevated baseline and follow-up hs-TnI served as significant independent predictors for MACE, with an increased risk of development being 8-tenfold. Furthermore, elevated baseline hs-TnI showed a predictive value for all-cause mortality. Central illustration: Novel immune checkpoint inhibitor (ICIs) therapy has been found to revolutionize cancer therapy through increased activation of host immune systems to target and reduce tumor burden, but may come at the cost of serious adverse cardiac events. Identification of early biomarkers for the prediction and detection of these events is necessary.

Radiation Therapy Before Repeat Wide Resection for Unplanned Surgery of Soft Tissue Sarcoma ("Oops" Operation) Results in Improved Disease-Free Survival.

Purpose: The main goal of treatment of soft-tissue sarcomas is achieving wide negative margins to improve local control and prevent recurrence. The role of radiation therapy (RT) is well established in sarcomas of the extremities; however, its role in unplanned surgery of soft-tissue sarcoma (when a mass presumed to be benign is resected and the pathology comes back as sarcoma, usually referred to as an "oops" operation) is inconclusive. This article reports on the effect of RT after an unplanned surgery before the reresection. Methods and Materials: A total of 65 patients who had undergone an unplanned resection of a postoperatively diagnosed soft-tissue sarcoma were treated with RT and/or surgery and retrospectively evaluated for disease progression. Treatment started with RT in 49 cases (75.4%), including 8 cases of no further surgery. A repeat wide resection was performed directly after the initial surgery in 16 patients, followed by RT in 15 of them. Results: The disease recurred in 7 out of 49 patients (14.3%) who received RT first and in 9 out of 16 (56.25%) who underwent reoperation before RT (P = .001). Disease-free progression was higher in cases of low-grade malignancy (P = .049). A clinical diagnosis of lipoma was associated with a better outcome than a diagnosis of nonlipoma (P = .034). The presence of residual tumor at reoperation did not affect disease control. Patient age, time between symptom onset and diagnosis, hospital level of initial diagnosis (tertiary versus nontertiary), anatomic site, tumor size, and margin status at the initial excisional biopsy were not significantly correlated with the outcome. Conclusion: Initiating treatment with RT followed by unplanned "oops" resection of soft-tissue sarcoma before the reresection improved disease-free survival as opposed to vice versa.

Implementation of Comprehensive Genomic Profiling in Ovarian Cancer Patients: A Retrospective Analysis.

Comprehensive genomic profiling (CGP) allows for the detection of driver alterations at high resolution, but the limited number of approved targeted therapies and their high costs have contributed to its limited clinical utilization. We retrospectively compared data of 946 women with ovarian cancer (11.4% were referred to CGP, and 88.6% served as control) to examine whether CGP provides a prognosis benefit. Patient baseline parameters were similar between the groups. Cox regression analysis adjusted for age, disease stage at diagnosis, and recurrence status showed statistically significantly longer median overall survival (mOS) in the CGP group versus the control (73.4 versus 54.5 months, p < 0.001). Fifty-four patients (52.9%) had actionable mutations with potential treatments; twenty-six (48.2%) were treated with matched targeted therapy, showing a trend for longer mOS than the eighty-six women in the CGP group who were not given a suggested treatment (105.5 versus 63.6 months, p = 0.066). None of the genomic alterations predicted metastasis location. CCNE1 amplification and KRAS mutations were associated with shorter mOS. Patients with tumor mutation burden ≥4 mutations/megabase had longer mOS. High loss of heterozygosity was associated with longer mOS (99.0 versus 48.2 months, p = 0.004). CGP testing may provide both prognostic and predictive insights for treatment of patients with ovarian cancer. Prospective studies of larger cohorts are warranted.

A prospective, controlled study of the botanical compound mixture LCS101 for chemotherapy-induced hematological complications in breast cancer.

BACKGROUND: This prospective, controlled study evaluated the safety, tolerability, and efficacy of the mixture of botanical compounds known as LCS101 in preventing chemotherapy-induced hematological toxicity in breast cancer patients. METHODS: Female patients diagnosed with localized breast cancer were randomly allocated to receive treatment with either LCS101 or placebo capsules, in addition to conventional chemotherapy. The study intervention was initiated 2 weeks prior to the initiation of chemotherapy and continued until chemotherapy was completed, with participants receiving 2 g of LCS101 capsules thrice daily. Subjects were assessed for the development of hematological and nonhematological toxicities, as well as the tolerability and safety of the study intervention. RESULTS: Sixty-five breast cancer patients were recruited, with 34 allocated to LCS101 and 31 allocated to placebo treatment. Patients in the treatment group developed significantly less severe (grades 2-4) anemia (p < .01) and leukopenia (p < .03) when comparing grades 0-1 with grades 2-4, with significantly less neutropenia (p < .04) when comparing grades 0-2 with grades 3-4. This effect was more significant among patients undergoing a dose-dense regimen. No statistically significant effect was found with respect to nonhematological toxicities, and side effect rates were not significantly different between the groups, with no severe or life-threatening events observed in either group. CONCLUSION: The addition of LCS101 to anthracycline- and taxane-based chemotherapy is safe and well tolerated, and may significantly prevent some chemotherapy-induced hematological toxicities in early breast cancer patients. These results should encourage further larger and more extensive clinical trials.
