RESUMO
BACKGROUND: Poly (ADP-ribose) polymerase inhibitors (PARPi) play a pivotal role in ovarian cancer management. With medical cannabis emerging as a novel component of supportive care, this study investigated the impact of medical cannabis use on oncological outcomes in patients with ovarian cancer undergoing PARPi therapy. METHODS: The study included patients from a single institution database treated for ovarian cancer between January 2014 and January 2020 who received PARPi maintenance therapy in a first-line or recurrent disease setting after a confirmed response to platinum-based treatment. The study categorized patients as cannabis users and cannabis-naïve. Univariate and multivariate Cox regression analysis and the Kaplan-Meier method were used to assess the effects of medical cannabis use on the duration of PARPi therapy, progression-free survival, and overall survival. RESULTS: Among the eligible patients (n=93), most were cannabis-naïve (69%, n=64) while the rest used medical cannabis (31%, n=29). Medical cannabis use rates were comparable for patients receiving PARPi therapy post-primary treatment or for recurrence (42%, n=9, vs 27%, n=20; p=0.1). Both groups exhibited similar median duration for PARPi therapy (12.1 vs 9.5 months; p=0.89) and progression-free survival (20 vs 21 months; p=0.83). Kaplan-Meier analysis detected no differences in progression-free survival associated with cannabis use. Although cannabis users had an extended overall survival compared with the cannabis-naïve group (129.3 vs 99 months; p=0.03), cannabis use was insignificant for overall survival on multivariate analysis (p=0.10). Multivariate analysis showed stage IV at diagnosis (p=0.02) to be the sole factor associated with progression-free survival (p=0.02). CONCLUSION: Medical cannabis usage in patients receiving PARPi treatment showed no association with duration of PARPi therapy, progression-free survival, or overall survival.

OBJECTIVE: To investigate the prognostic significance of near-complete metabolic response on initial follow-up PET/CT after primary chemoradiation treatment of cervical cancer. METHODS: Survival data were retrospectively compared between patients who had complete metabolic response on first follow-up PET/CT, 3 months after chemoradiation (group 1) with those who had near-complete metabolic response on first PET/CT and later showed complete metabolic response at subsequent PET/CT, 6 months or more after treatment (group 2). RESULTS: Of the 108 patients included in the final analysis, 74 (68.5%) showed complete metabolic response on initial PET/CT, 3 months after treatment, and 34 patients (31.5%) showed complete metabolic response on subsequent PET/CT, 6 months after treatment. Tumor characteristics were comparable between groups. Group 1 had higher percent of stage 1 (12% vs 0%) and lower percent of stage 4 disease (3% vs 14%) than those of group 2. Group 2 patients had significantly fewer cases of recurrences and deaths than group 1 patients (6% vs 26%, p=0.018; 0% vs 20%, p=0.003, respectively), with comparable 3-year survival rates (group 1, 90% vs group 2, 100%, p=0.31). Twelve patients had progressive disease on first follow-up PET/CT; these patients had significantly worse overall survival compared with all other patients (log-rank test, p<0.001). Younger age and delayed complete metabolic response were associated with lower chance of recurrence and death on univariate analysis. On multivariate analysis, delayed complete metabolic response remained significantly associated with no recurrence HR=0.14 (95% CI 0.25 to 0.84), p=0.031. CONCLUSIONS: Survival outcome of patients with cervical cancer who show residual 18F-fluorodeoxyglucose uptake on initial PET/CT after treatment, but reach complete metabolic response on follow-up PET/CT, is not inferior compared with survival of patients who show complete metabolic response on initial PET/CT 3 months after treatment. Watchful waiting with follow-up PET/CT seems a safe option for these patients.

OBJECTIVE: Our study aimed to explore the effect of body mass index (BMI) change on cancer recurrence risk during the routine surveillance of endometrial cancer patients. METHODS: Data on patients with endometrial adenocarcinoma that had a staging procedure and continued follow-up was retrospectively collected. We compared patients' BMI at time of surgery and during the last clinic follow-up. Univariate and multivariate analyses were performed to examine the effect of predictors on BMI change and the risk of recurrence. RESULTS: A total of 211 patients were included in the final analysis. The majority of patients had stage I disease (n=176, 89%) and endometrioid histology (n=178, 86%). Median follow-up time was 53.4 (standard deviation (SD) 40) months. The mean BMI was 30.4 kg/m2 (interquartile range (IQR) 25-34) at surgery compared with 30.9 kg/m2 (IQR 26-36) at last follow-up (p<0.001). The BMI increase was most pronounced in patients with endometroid histology that recurred, 31.6 (IQR 24-35) kg/m2 at surgery compared with 33.5 (IQR 27-36) kg/m2 at last follow-up (p=0.016). On multivariate analysis, age and BMI change were the only predictors that were significantly associated with the risk of recurrence (overall response (OR 1.07 (0.99-1.14), p=0.05, OR 1.37 (1.12-1.67), p=0.002, respectively). CONCLUSION: Patients with endometroid endometrial cancer that had an increase in BMI during follow-up were at an increased risk for cancer recurrence compared with patients that did not change or had a decrease in BMI.

OBJECTIVE: The use of chemoradiation in patients with stage IVB cancer of the cervix was evaluated to determine if definitive treatment offers benefit. METHODS: A database of 546 patients with cancer of the cervix treated between January 2005 and May 2021 at a tertiary academic medical center was reviewed retrospectively to identify patients with stage IVB disease. Log rank test, regression analysis, and the Kaplan-Meier method were used to identify and compare variables and estimate progression free survival and overall survival. RESULTS: Thirty-three patients with stage IVB cervical cancer were identified. Median age was 53 years (range 28-78). Pathology subtypes were squamous cell (n=22, 67%), adenocarcinoma (n=8, 24%), and clear cell (n=3, 9%). Metastases were classified as lymphatic (n=14, 42%) or hematogenous (n=19, 58%). Following treatment to all sites with chemoradiotherapy and selected use of surgery (n=23), six patients (26%, lymphatic n=4, hematogenous n=2) remained disease free for a median duration of 4 years (range 3-17 years). Recurrences in the remaining patients were distant (n=13) or local (n=4). All patients in the chemotherapy group (n=10, 100%) progressed. Kaplan-Meier analysis showed that median progression free survival was longer for patients treated at all disease sites than for patients treated with chemotherapy alone (19 vs 11 months, p=0.01). However, this was not the case for overall survival (49 vs 33 months, p=0.15). Patients with metastases limited to lymph nodes also had longer median progression free survival (22 vs 11 months, p=0.04) but not overall survival (p=0.68). CONCLUSIONS: Patients with stage IVB cancer of the cervix may benefit from treatment to all sites of disease, if feasible and safe, as demonstrated by improved progression free survival.

BACKGROUND: Brain metastasis (BM) are uncommon among women with epithelial ovarian cancer (EOC). The frequency, risk factors and clinical repercussions of BM in these patients are not well described. METHODS: We retrospectively evaluated EOC patients treated at our center from 2002 to 2020 and assessed their clinical parameters, risk for BM development and association with overall survival (OS). This cohort has a known high frequency of BRCA mutation carriers (BRCAm) due to women of Ashkenazi Jewish descent. RESULTS: Among 1035 EOC patients, 29 (2.8%) were diagnosed with BM. The prevalence of BRCA mutations was more common among women with BM (56.5% vs. 34.3%, p = 0.033). The BM rate in patients with BRCAm was higher than the BM rate in those with wildtype BRCA (BRCAw; 5.1% vs. 2.1%, OR = 2.6; 95% CI: 1.2-5.4, p = 0.013). Median time from diagnosis to BM and from disease recurrence to BM was longer among patients with BRCAm. Median OS was not significantly different among patients with BM versus those without BM (59.4 vs. 73.4 months, p = 0.243). After BM diagnosis, median OS was not statistically significantly different between patients with BRCAm and those with BRCAw (20.6 vs. 12.3 months, p = 0.441). Treatment with poly (ADP-ribose) polymerase inhibitors and bevacizumab had no impact on subsequent development of BM. CONCLUSIONS: BM are rare among EOC patients. However, the risk is three-fold higher among patients with BRCAm. BM do not significantly alter OS among EOC patients. The higher rate of BM in patients with BRCAm may be related to longer OS in this subpopulation.

INTRODUCTION: Extrapulmonary small-cell cancer (EPSCC) is a relatively rare malignancy. The management of EPSCC is usually extrapolated from small-cell lung cancer (SCLC). In spite of the morphological similarity of the 2 malignancies, there are many differences in clinical features, prognosis, and recommendations of treatment of these disorders. The data on the correlation of clinical-pathological characteristics of EPSCC and treatment results is scarce. MATERIALS AND METHODS: This retrospective analysis of 41 consecutively treated patients diagnosed with EPSCC in 2015-2018 was performed in a tertiary medical center. The correlation between the clinical and pathological characteristics and the treatment outcome (response rate, disease-free interval, and overall medial survival) was done using the standard statistics, Kaplan-Meier method, and multivariate analyses. The stratification was done on the stage of the disease, Ki-67 proliferative index, the location of the tumor, and smoking. RESULTS: Forty-one patients were included with a median age of 66.3 years. The most common primary site was the gastrointestinal tract (28, 68.3%) including the pancreas. The most common distant metastasis site was the liver (23, 56.1%). Only 2 patients (4.9%) had brain metastases. Unlike in SCLC, most patients did not have any history of smoking (23, 56.1%). Nineteen patients with metastatic disease received systemic treatment, mostly cisplatin-based chemotherapy, with a response rate of 57.9%. The results of treatment were significantly better in patients with disseminated EPSCC with Ki-67 <55%, while its role in limited disease was nonsignificant. DISCUSSION: The results of our study show the unique entity of EPSCC. The rarity of brain metastases proves that prophylactic brain irradiation should not be recommended in practice. The provocative idea of prophylactic liver irradiation in limited-stage EPSCC of gastrointestinal origin can be evaluated in future studies. The predictive role of Ki-67 is important in metastatic EPSCC. There is probably no role of smoking in developing EPSCC.

BACKGROUND: Gynecologic oncologists should be aware of the option of conception through IVF/PGT-M for families with high BRCA related morbidity or mortality. Our objective was to investigate the cost-effectiveness of preimplantation genetic testing for selection and transfer of BRCA negative embryo in BRCA mutation carriers compared to natural conception. METHODS: Cost-effectiveness of two strategies, conception through IVF/PGT-M and BRCA negative embryo transfer versus natural conception with a 50% chance of BRCA positive newborn for BRCA mutation carriers was compared using a Markovian process decision analysis model. Costs of the two strategies were compared using quality adjusted life years (QALYs'). All costs were discounted at 3%. Incremental cost effectiveness ratio (ICER) compared to willingness to pay threshold was used for cost-effectiveness analysis. RESULTS: IVF/ PGT-M is cost-effective with an ICER of 150,219 new Israeli Shekels, per QALY gained (equivalent to 44,480 USD), at a 3% discount rate. CONCLUSIONS: IVF/ PGT-M and BRCA negative embryo transfer compared to natural conception among BRCA positive parents is cost effective and may be offered for selected couples with high BRCA mutation related morbidity or mortality. Our results could impact decisions regarding conception among BRCA positive couples and health care providers.

INTRODUCTION: Current international guidelines, including the Choosing Wisely Initiative, recommends against the routine use of systemic imaging studies or tumor markers in early-stage breast cancer. Accumulating data suggests that adherence to these guidelines is low. We aimed to investigate the execution of unnecessary diagnostic tests among Israeli breast cancer patients and identify factors associated with their performance. METHODS: A retrospective analysis was conducted involving a database of early breast cancer patients treated at Tel Aviv Sourasky Medical Center. A survey was distributed among Israeli surgeons and oncologists specializing in breast cancer treatment. RESULTS: The study included early breast cancer patients (n = 178), who have no indication for completing systemic evaluation. Nearly half of the patients (76, 42%) were referred to 128 unjustified diagnostic studies, with the most common referral comprising a PET-CT (n = 39 30.5%). As expected, none of the tests led to any change in either disease staging or alteration in clinical management. Variables associated with systemic evaluation included younger age (61.8% for < 50 years vs 38.9% for > 50 years, p = 0.02), diagnosis by palpable mass compared to screening mammography (26.9% vs 52.9% p = 0.043, respectively) and higher tumor grade (33.7% vs 52.2% p = 0.02, respectively). In concordance with the findings of the database, the physicians' survey revealed low adherence to guidelines and a role of the treating physicians' subjective feelings. Doctors were more likely to recommend unnecessary studies when presented with a clinical case as an image, than to an informative question. CONCLUSIONS: Our data indicate a high rate of non-adherence to guidelines, physicians recommending extensive systemic evaluation for women with early breast cancer. These deviations from the guidelines are associated with subjective factors, some of them being physician-dependent. Initiatives aimed at improving adherence to guidelines, and specifically to guidelines recommending "doing less" should therefore include not just knowledge-based education but also encourage conversation about what is appropriate and necessary.

We aimed to investigate the cost-effectiveness of open surgery, compared to minimally invasive radical hysterectomy for early-stage cervical cancer, using updated survival data. Costs and utilities of each surgical approach were compared using a Markovian decision analysis model. Survival data stratified by surgical approach and surgery costs were received from recently published data. Average costs were discounted at 3%. The value of health benefits for each strategy was calculated using quality-adjusted life years (QALYs). Incremental cost-effectiveness ratio, calculated using the formula (average cost minimal invasive surgery-average cost open surgery)/(average QALY minimal invasive surgery-average QALY open surgery), was used for cost-effectiveness analysis. One-way sensitivity analysis was conducted for all variables. Open radical hysterectomy was found to be cost-saving compared to minimally invasive surgery with an incremental cost-effectiveness ratio of USD -66 and USD -373 for laparoscopic and robotic surgery, respectively. The most influential parameters in the model were surgery costs, followed by the disutility involved with open surgery. Until further data are generated regarding the survival of patients with early-stage cervical cancer treated by minimally invasive surgery, at current pricing, open radical hysterectomy is cost-saving compared to minimally invasive radical hysterectomy, both laparoscopic and robotic.
RESUMO
Objective: To evaluate the effectiveness and safety of standard chemotherapy administered to patients >70 years with advanced ovarian cancer (OC). Methods: Medical records of 956 advanced-stage patients with OC treated between 2002-2020 with standard surgery and paclitaxel-carboplatin chemotherapy in a three-weekly (PC-3W) or weekly (PC-1W) regimen were reviewed. Treatment response and tolerability were compared between patients ≤70 years (N=723) and >70 years (N=233) with stratification to septuagenarians (>70-80 years) and octogenarians (>80 years). Results: Median overall survival (mOS) in patients >70 was 41.26 months (95% confidence interval [Cl], 37.22-45.14) and median progression-free survival (mPFS) was 11.04 months (95% Cl, 8.97-15.74). No statistically significant differences in mPFS and mOS were observed between septuagenarians and octogenarians. Patients >70 treated with PC-1W versus PC-3W had significantly longer mOS (57.17 versus 30.00 months) and mPFS (19.09 versus 8.15 months). Toxicity rates were mostly similar between younger and older patients. Among patients >70 treated with PC-1W, the rate of neutropenia (75.7% versus 51.8%, p=0.0005), thrombocytopenia (41.0% versus 22.2%, p=0.0042) and anemia (78.1% versus 51.9%, p<0.0001) were significantly higher and the rate of grade 2 alopecia was statistically significantly lower compared with those >70 treated with PC-3W. Significantly more patients treated with PC-1W completed ≥6 chemotherapy cycles, suggesting better tolerability of this regimen. Conclusions: Older patients with OC may benefit from improved OS with reasonable toxicity if treated with standard chemotherapy. Older patients treated with PC-1W are more likely to complete the full chemotherapy course and survive longer compared with those treated with conventional PC-3W.
RESUMO
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.
RESUMO
Kambô is a cleansing ritual involving the application of a toxin produced by the giant leaf frog (Phyllomedusa bicolor). The Kambô ritual has increasingly been adopted among cancer patients in Europe. Accumulating data indicate various adverse effects. We report another severe adverse reaction to Kambô, a systemic inflammatory response syndrome mimicking disease progression in a patient with cholangiocarcinoma. We describe a systemic reaction to Kambô, manifested as tachycardia, tachypnea, impaired liver cholestatic enzymes, and enlargement of lymphadenopathy mimicking disease progression. The clinical features and onset of symptoms, the rapid reaction, and the lack of other identified causes make the diagnosis of Kambô-induced SIRS highly probable. This case report calls for future studies examining standard oncological care such as chemotherapy, radiotherapy, and immunotherapy in conjunction with alternative therapy. Additionally, greater awareness and physician education should be promoted, encouraging inquiry of oncology patients' administration of alternative, complementary, and integrative medicine.

OBJECTIVE: To examine whether patients with both breast cancer (BC) and endometrial cancer (EC) have different features of disease, and whether the sequence of appearance of these tumors is correlated with a more aggressive course. METHODS: A retrospective, multi-center observational cohort study of patients treated in two tertiary medical centers between 2014 and 2020. Files of patients who had a co-diagnosis of BC and EC were reviewed and clinical, epidemiological, pathological and genetic characteristics were collected. RESULTS: 67 patients with a co-diagnosis of both malignances were divided into two groups according to primary tumor diagnosis: BC first group (43/67, 64%) and EC first group (24/67, 36%). The time interval between diagnosis of malignancies was significantly longer in the BC first group (mean 144.5 months vs. 67 months, p < 0.05). BRCA mutations were found in higher numbers in the BC first group (27.5% vs. 9.5%, p = 0.18). A significantly higher number of patients in the BC first group had uterine serous carcinoma (USC) histology (44% vs. 12.5%, p < 0.05). This was independent of tamoxifen usage among patients (OR 0.65, 95% CI 0.17-2.49). CONCLUSIONS: In patients suffering from both BC and EC, the sequence of occurrence of malignancies has relevance: When EC presents as a second primary tumor, it tends to present in a more aggressive form, independent of previous tamoxifen use. The time interval between the diagnosis of malignancies was significantly longer in this group, offering an opportunity to improve preventive measures to decrease the likelihood of a subsequent lethal second cancer.
RESUMO
The widespread use of immune checkpoint inhibitors (ICI) has become a mainstay of care for a variety of malignancies. However, these therapies portend a range of adverse effects, including a potentially fatal form of cardiotoxicity which to date has not been elucidated. We aimed to evaluate the baseline characteristics of ICI-mediated cardiotoxicity. We performed a retrospective study evaluating patients treated with ICI who performed at least 2 echocardiography examinations, before and after the initiation of ICI. Cardiotoxicity was defined as Cancer Therapeutics-related Cardiac Dysfunction (CTRCD) development, with an absolute left ventricular ejection fraction reduction of >10%, to a value <53%. Fifty-two patients were included with a male preponderance (65%) and a mean age of 66 (±12) years. Twelve (23%) patients developed CTRCD, of which 2 patients were diagnosed with myocarditis. Among the CTRCD group, patients tended to be older and more likely to have baseline diastolic dysfunction: lower e' septal (P=0.026), higher E/e' septal (P=0.035), and a trend of E/e' average (P=0.076). All-cause and cardiovascular hospitalizations were significantly more common among the CTRCD group (P=0.028 and 0.001, respectively). Higher prevalence of cardiovascular mortality was observed among the CTRCD group (25% vs. 2%, P=0.034). We evaluated the development of CTRCD among patients treated with ICI therapies. Our findings suggest that baseline diastolic parameters may be associated with CTRCD development assisting in the early diagnosis of ICI-induced cardiac injury.

BACKGROUND: Immune checkpoint inhibitors (ICI) have transformed the standard care of cancer treatment. Recent case reports describe ICI-mediated myocarditis with an atypical presentation and fatal potential which lead to permanent interruption of immunotherapy. OBJECTIVES: To characterize ICI-mediated myocarditis and re-introduction to immunotherapy. METHODS: During 2019, 849 patients were treated with ICI at Tel Aviv Sourasky Medical Center for the diagnosis of lung adenocarcinoma, gastric adenocarcinoma, urothelial carcinoma, and hepatocellular carcinoma. Overall, seven (0.8%) patients were diagnosed with ICI-mediated myocarditis, according to the European Society of Cardiology guidelines of myocarditis 2013. We retrospectively evaluated their presentation, severity, and clinical outcomes. RESULTS: Among the seven patients, only one had a history of cardiac disease. The majority were diagnosed with lung adenocarcinoma and treated with anti-programmed death-1 antibody. All patients were treated with single-agent ICI. Most patients presented with cardiac symptoms, elevated troponin and typical cardiac magnetic resonance; however, only three had reduced ejection fraction. Overall, three patients were chosen for re-introduction with concomitant low dose steroids and weekly troponin follow-up. Two patients diagnosed with grade I and II renewed therapy successfully with no recurrence of symptoms and improvement in disease burden. The one patient diagnosed with grade III developed worsening of cardiac symptoms after the 1st cycle and, therefore, therapy was interrupted permanently. CONCLUSIONS: ICI-mediated myocarditis is potentially fatal and leads to permanent interruption of life-saving cancer therapy. The current data suggest that re-introduction may be considered in low-grade patients; however, a better definition of the diagnosis and grading is needed.

Hereditary breast cancer syndromes affect a small (10-15% of cases) but significant group of patients. BRCA1 and BRCA2 are the most familiar and well-studied genes associated with inherited breast cancer. However, mutations in the high-penetrance genes, TP53, PTEN, CDH1, MSH1, MLH1, MSH6, PMS2, PALB2, and STK11, and in the moderate-penetrance genes, CHEK2, ATM, and BRIP1, also correlate with high lifetime risks of breast cancer and other malignancies as well. Advances in breast cancer genetics have led to an improved perception of diagnosis and screening strategies. The specific considerations and challenges involved in treating this unique population have become a fertile ground for research. Indeed, these genes and downstream molecular pathways have now become potential therapeutic targets in breast cancer patients, including those with BRCA1 or BRCA2 mutations. This review describes the variety of hereditary breast cancer genes, from their molecular origins to the prognosis and multidisciplinary clinical decision-making processes. Key publications and other reported recent clinical trials and guidelines are provided.
