RESUMO

The optimal therapy for patients with non-metastatic biochemically relapsed prostate cancer (BRPC-M0) after local therapy is elusive. Thus, the evaluation of new non-toxic compounds in BRPC-M0 patients is warranted. PectaSol®-Modified citrus pectin (P-MCP) is a food supplement categorized as GRAS (Generally Recognized As Safe) by the FDA. It is a competitive inhibitor of the galectin-3 protein, which is involved in cancer pathogenesis. In an early report of the present phase 2 study, P-MCP treatment for 6 months led to prostate-specific antigen doubling time (PSADT) improvement in 75% of patients with BRPC-M0. Herein, we report the second long-term treatment phase of an additional 12 months of P-MCP therapy (4.8 g × 3/day orally) in patients without disease progression after the initial 6 months of therapy. Of the 46 patients that entered the second treatment phase, 7 patients withdrew consent and decided to continue therapy out of pocket, and 39 initiated the second treatment phase. After a total of 18 months of P-MCP treatment, 85% (n = 33) had a durable long-term response, with 62% (n = 24) showing decreased/stable PSA, 90% (n = 35) PSADT improvement, and all with negative scans. No patient had grade 3/4 toxicity. In conclusion, P-MCP may have long-term durable efficacy and is safe in BRPC-M0.

RESUMO

PURPOSE: Cancer is the second leading cause of death globally. However, by implementing evidence-based prevention strategies, 30%-50% of cancers can be detected early with improved outcomes. At the integrated cancer prevention center (ICPC), we aimed to increase early detection by screening for multiple cancers during one visit. METHODS: Self-referred asymptomatic individuals, age 20-80 years, were included prospectively. Clinical, laboratory, and epidemiological data were obtained by multiple specialists, and further testing was obtained based on symptoms, family history, individual risk factors, and abnormalities identified during the visit. Follow-up recommendations and diagnoses were given as appropriate. RESULTS: Between January 1, 2006, and December 31, 2019, 8,618 men and 8,486 women, average age 47.11 ± 11.71 years, were screened. Of 259 cancers detected through the ICPC, 49 (19.8%) were stage 0, 113 (45.6%) stage I, 30 (12.1%) stage II, 25 (10.1%) stage III, and 31(12.5%) stage IV. Seventeen cancers were missed, six of which were within the scope of the ICPC. Compared with the Israeli registry, at the ICPC, less cancers were diagnosed at a metastatic stage for breast (none v 3.7%), lung (6.7% v 11.4%), colon (20.0% v 46.2%), prostate (5.6% v 10.5%), and cervical/uterine (none v 8.5%) cancers. When compared with the average stage of detection in the United States, detection was earlier for breast, lung, prostate, and female reproductive cancers. Patient satisfaction rate was 8.35 ± 1.85 (scale 1-10). CONCLUSION: We present a proof of concept study for a one-stop-shop approach to cancer screening in a multidisciplinary outpatient clinic. We successfully detected cancers at an early stage, which has the potential to reduce morbidity and mortality as well as offer substantial cost savings.[Media: see text].

RESUMO

Optimal therapy of biochemically relapsed prostate cancer (BRPC) after local treatment is elusive. An established modified citrus pectin (PectaSol®, P-MCP), a dietary polysaccharide, is an established antagonist of galectin-3, a carbohydrate-binding protein involved in cancer pathogenesis. Based on PSA dynamics, we report on the safety and the primary outcome analysis of a prospective phase II study of P-MCP in non-metastatic BRPC based. Sixty patients were enrolled, and one patient withdrew after a month. Patients (n = 59) were given P-MCP, 4.8 grams X 3/day, for six months. The primary endpoint was the rate without PSA progression and improved PSA doubling time (PSADT). Secondary endpoints were the rate without radiologic progression and toxicity. Patients that did not progress by PSA and radiologically at six months continued for an additional twelve months. After six months, 78% (n = 46) responded to therapy, with a decreased/stable PSA in 58% (n = 34), or improvement of PSADT in 75% (n = 44), and with negative scans, and entered the second twelve months treatment phase. Median PSADT improved significantly (p = 0.003). Disease progression during the first 6 months was noted in only 22% (n = 13), with PSA progression in 17% (n = 10), and PSA and radiologic progression in 5% (n = 3). No patients developed grade 3 or 4 toxicity.

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.

RESUMO

Hodgkin lymphoma (HL) is one of the most curable malignancies. Despite its effectiveness, chemotherapy is often associated with adverse events (AEs) such as nausea, anorexia, and impairment of general well-being. Our objective was to assess the extent of medical cannabis use among HL patients and evaluate its efficacy in controlling chemotherapy-related AEs. Patterns of medical cannabis use and efficacy were evaluated using physician-completed application forms, medical files, and patient-completed questionnaires, for all consecutive adult HL patients treated at the Tel-Aviv Medical Center between June 2010 and November 2016. One-hundred and thirty-three patients met the inclusion criteria. The median age of the cohort was 37 years, 53% were male, 46% were diagnosed at an early stage, and 88% achieved a complete response to treatment. Fifty-one patients (38%) used medical cannabis. There were no significant differences in baseline characteristics between cannabis users and nonusers. Cannabis users reported improvement in pain, general well-being, appetite, and nausea in 94, 87, 82, and 79% of cases, respectively. Importantly, 81.5% reported a high overall efficacy of cannabis in relieving symptoms. AEs related to cannabis use itself were mild. Thus, medical cannabis use is prevalent in this HL cohort, and appears to be effective in ameliorating chemotherapy-related AEs.

RESUMO

OBJECTIVE: To assess clinical and pathologic efficacy of neoadjuvant FOLFIRINOX for locally advanced (LAPC) and borderline resectable pancreatic cancer (BRPC). METHODS: Patients receiving neoadjuvant FOLFIRINOX for LAPC and BRPC treated between 2014 and 2017 were identified. Post-treatment patients achieving resectability were referred for surgery, whereas unresectable patients continued chemotherapy. Clinical and pathological data were retrospectively compared with control group consisting of 47 consecutive patients with BRPC undergoing pancreatic and portal vein resection between 2008 and 2017. RESULTS: Thirty LAPC and 23 BRPC patients were identified. Reasons for unresectability included disease progression (70%), locally unresectable disease (18%), and poor performance status (11%). Three patients (10%) with LAPC, and 20 (87%) with BRPC underwent curative surgery. Compared with control group, perioperative complication rate (4.3% versus 28.9%, p = 0.016), and pancreatic fistula rate (0 versus 14.8%, p = 0.08) were lower. Peripancreatic fat invasion (52.2% vs 97.8%, p = 0.001), lymph node involvement (22% vs 54.3%, p = 0.01), and surgical margin involvement (0 vs 17.4%, p = 0.04) were higher in the control group. Median survival was 34.3 months in BRPC patients operated after FOLFIRINOX and 26.1 months in the control group (p = 0.07). Three patients (13%) with complete pathological response are disease-free after mean follow-up of 19 months. CONCLUSIONS: Whereas neoadjuvant FOLFIRINOX rarely achieves resectability in patients with LAPC (10%), most BRPC undergo resection (87%). Neoadjuvant FOLFIRINOX leads to complete pathological response in 13% of cases, tumor downstaging, and a trend towards improved survival compared with patients undergoing up-front surgery.

RESUMO

BACKGROUND & AIMS: Klotho is a trans-membrane protein which can be shed to act as a hormone; its blood levels may be regulated by the GH/IGF-1 axis. Klotho deficient mice exhibit short lifespan and characteristics of aging and malnutrition, including decreased fat and muscle mass, osteopenia, and impaired fertility. As anorexia nervosa (AN) is characterized by malnutrition and GH resistance, we hypothesized klotho levels would be altered in AN, and aimed to assess klotho levels in undernourished AN patients and changes in klotho following weight rehabilitation. PARTICIPANTS AND METHODS: 19 adolescent female AN inpatients (aged 16.1 ± 1.8 years) admitted to an inpatient service for eating disorders in a tertiary center were recruited. Blood samples were obtained on admission and after weight restoration (interval 4.0 ± 2.3 months) and analyzed for klotho, IGF-1, calcium, phosphorus, and alkaline phosphatase. RESULTS: Klotho levels on admission were lower than expected for age, and correlated with lumbar spine BMD Z-score (r = -0.81, p < 0.001) and alkaline phosphatase levels (r = 0.66, p = 0.003) but not with age, height-SDS, weight-SDS, BMI-SDS, or serum calcium, phosphorus and IGF-1 levels. Both IGF-1 and klotho levels increased significantly during hospitalization (IGF-1: 44 ± 17 nmol/l to 53 ± 11 nmol/l, p = 0.008; klotho: 1061 ± 421 pg/ml to 1519 ± 781 pg/ml, p = 0.008). CONCLUSIONS: Klotho levels are low in the acute stage of AN and increase with nutritional rehabilitation. Low klotho on admission may be secondary to low IGF-1 levels and may contribute to the clinical manifestations of AN. The role of klotho in the pathophysiology of AN and as a novel marker of disease severity should be further explored.

RESUMO

CONTEXT: The use of the cannabis plant (Cannabis sativa L.) for the palliative treatment of cancer patients has been legalized in multiple jurisdictions including Israel. Yet, not much is currently known regarding the efficacy and patterns of use of cannabis in this setting. OBJECTIVES: To analyze the indications for the administration of cannabis among adult Israeli cancer patients and evaluate its efficacy. METHODS: Efficacy and patterns of use of cannabis were evaluated using physician-completed application forms, medical files, and a detailed questionnaire in adult cancer patients treated at a single institution. RESULTS: Of approximately 17,000 cancer patients seen, 279 (<1.7%) received a permit for cannabis from an authorized institutional oncologist. The median age of cannabis users was 60 years (range 19-93 years), 160 (57%) were female, and 234 (84%) had metastatic disease. Of 151 (54%) patients alive at six months, 70 (46%) renewed their cannabis permit. Renewal was more common among younger patients and those with metastatic disease. Of 113 patients alive and using cannabis at one month, 69 (61%) responded to the detailed questionnaire. Improvement in pain, general well-being, appetite, and nausea were reported by 70%, 70%, 60%, and 50%, respectively. Side effects were mild and consisted mostly of fatigue and dizziness. CONCLUSION: Cannabis use is perceived as highly effective by some patients with advanced cancer and its administration can be regulated, even by local authorities. Additional studies are required to evaluate the efficacy of cannabis as part of the palliative treatment of cancer patients.

RESUMO

Posterior reversible leukoencephalopathy syndrome [PRES] is characterized by a symmetrical brain edema. It is rarely caused by chemotheraphy. While steroids can lead to deterioration in the condition of a PRES patient, they are still the drug of choice for the more common condition of brain edema secondary to metastases. We describe the case of a colon cancer patient who underwent adjuvant treatment with capecitabine and oxaliplatin and was admitted to the hospital with seizures and brain edema. On admission, the condition was attributed to brain metastases and hence a high dose steroid treatment was initiated. Later on, as the patient became comatose, the CT was revised and PRES was suggested as an alternative diagnosis. After tapering the steroids the patient gradually recovered. This report emphasizes the need to be alert and not to confuse PRES with brain metastasis in cancer patients.
