Beyond traditional therapies: clinical significance of complex molecular profiling in patients with advanced solid tumours-results from a Turkish multi-centre study.

OBJECTIVE: The objective of this multi-centre, real-world study was to examine the potential influence of comprehensive molecular profiling on the development of treatment decisions or adjustments for patients with advanced solid malignancies. We then evaluated the impact of these informed choices on patient treatment outcomes. METHODS: The study encompassed 234 adult patients (mean age: 52.7 ± 14.3 years, 54.7% women) who were diagnosed with solid tumours at 21 different medical centres in Turkey. Remarkably, 67.9% of the patients exhibited metastasis at the time of diagnosis. We utilized an OncoDNA (Gosselies, Belgium) platform (OncoDEEP) integrating next-generation sequencing with additional tests to harvest complex molecular profiling data. The results were analyzed in relation with two specific outcomes: (i) the impact on therapeutic decisions, including formulation or modifications, and (ii) associated treatment response. RESULTS: Out of the 228 patients with final molecular profiling results, 118 (50.4%) had their treatment modified, whilst the remaining 110 (47.0%) did not. The response rates were comparable, with 3.9 versus 3.4% for complete response, 13.6 versus 29.3% for partial response, 66.9 versus 51.7% for progressive disease and 15.5 versus 15.5% for stable disease for treatments informed and not informed by complex molecular profiling, respectively (P = 0.16). CONCLUSION: Our real-world findings highlight the significant impact of complex molecular profiling on the treatment decisions made by oncologists for a substantial portion of patients with advanced solid tumours. Regrettably, no significant advantage was detected in terms of treatment response or disease control rates.

Sorafenib with TACE improves the survival of hepatocellular carcinoma patients with more than 10 cm tumor: a single-center retrospective study.

PURPOSE: Sorafenib, a multikinase inhibitor, is effective in patients with advanced hepatocellular carcinoma (HCC). Transarterial chemoembolization (TACE) is an important palliative treatment for unresectable HCC, but TACE-induced ischemic injury can upregulate angiogenic factors and it might be associated with poor prognosis. The purpose of this study was to evaluate the efficacy of conventional TACE with or without sorafenib in patients with Barcelona Clinic Liver Cancer (BCLC) stage A-B HCC. METHODS: Thirty patients with BCLC stage A or B HCC who had undergone TACE were enrolled in this retrospective study. Child-Pugh score, BCLC staging classification, size and number of lesions were recorded. Sorafenib was given 1 month after TACE to some patients who responded to TACE. Repeated TACE was performed on demand. Tumor response was assessed every 12 weeks. The primary objective of this trial was the progression free survival (PFS). Secondary objectives were overall survival (OS), disease control rate (DCR) and total number of TACE interventions. Kaplan-Meier method was used for the estimation of survival and survival curves were compared with Log-rank test. RESULTS: Twenty-five (83.3%) patients had Child-Pugh A and 5 (16.7%) Child-Pugh B, and 24 (80%) patients had BCLC stage B disease and remanining had stage A disease. Lesion size >10 cm was found in 6 patients and 16/7/7 patients had single/two/multiple lesions, respectively. Mean number of TACE was 2.10±1.369. Seventeen (56.7%) patients used sorafenib after TACE whereas 13 (43.3%) patients were followed without any treatment but received consequent TACEs if needed. PFS of all patients was 10 months (range 3-48); it was 13 months for TACE plus sorafenib group and 9 months for TACE group (p=0.081). In subgroup analysis, TACE plus sorafenib group had better PFS (36 vs 12 months) in patients with tumor size > 10 cm (p=0.025). In the analysis of Child- Pugh A cases, PFS of TACE plus sorafenib group was 23 months while it was 10 months in TACE group (p=0.007). CONCLUSION: Concurrent treatment in Child-Pugh A group HCC with conventional TACE and sorafenib demonstrates a significant efficacy in patients having tumor size >10 cm. In Child-Pugh A group, PFS was superior in the sorafenib plus TACE group than in TACE alone group.

Prognostic factors and adjuvant treatments for surgically treated cancers of the biliary tract: a multicentre study of the Anatolian Society of Medical Oncology (ASMO).

BACKGROUND: Biliary tract cancers are rare, and surgical resection is the standard treatment at early stages. However, reports on the benefits of adjuvant treatment following surgical resection are conflicting. This study aimed to evaluate the factors affecting survival and adjuvant treatments in patients with surgically treated biliary tract cancers. MATERIALS AND METHODS: Patient clinical features, adjuvant treatments, and efficacy and prognostic factor data were evaluated. Survival analyses were performed using SPSS 15.0. RESULTS: The median overall survival was 30.7 months (95% confidence interval [CI], 18.4-42.9 months). Median survival was 19 months (95% CI, 6-33) for patients treated with fluorouracil based chemotherapy and 53 months (95% CI, 33.2-78.8) with gemcitabine based chemotherapy (p=0.033). On univariate analysis, poor prognostic factors for survival were galbladder localization, perineural invasion, hepatic invasion, a lack of adjuvant chemoradiotherapy treatment, and a lack of lymph node dissection. On multivariate analysis, perineural invasion was a poor prognostic factor (p=0.008). CONCLUSIONS: Biliary tract cancers generally have poor prognoses. The main factors affecting survival are tumour localization, perineural invasion, hepatic invasion, adjuvant chemoradiotherapy, and lymph node dissection. Gemcitabine-based adjuvant chemotherapy is more effective than 5-fluorouracil-based chemotherapy.

The effect of aromatherapy and massage administered in different ways to women with breast cancer on their symptoms and quality of life.

The primary objective of this study was to assess the effect of aromatherapy and classic massage administered in various ways to breast cancer patients on their symptoms and quality of life. The sampling consisted of 280 patients. Quality of life and symptoms of the patients were evaluated once at baseline and then at week 6 and week 10 following the intervention. After intervention, the control group was observed to have lower total quality of life score and subdomain scores, whereas fragrance, massage and aromatherapy massage groups had higher scores, and the increase was more obvious particularly in the patients in the aromatherapy massage group. Similarly, whereas psychological and physical symptoms were experienced more intensely in the control group, the severity of all the symptoms experienced by the other patients decreased at week 6 and week 10 as compared with baseline especially in the group that was administered massage with aromatherapy.

Depression, anxiety and quality of life through the use of complementary and alternative medicine among breast cancer patients in Turkey.

BACKGROUND AND AIM: Breast cancer is the most common type of cancer amongst women today. The aim of this study was to examine the association between complementary and alternative medicine (CAM) and the quality of life (QoL), anxiety and depression and demographic characteristics of women with breast cancer. MATERIALS AND METHODS: QoL was measured by the European Organization for Treatment and Research of Cancer quality of life core questionnaire (QLQ-C30, version 3.0) and anxiety and depression was measured by the hospital anxiety and depression scale. RESULTS: In total, 122 patients with breast cancer were enrolled in the study and 50% (n=61) of them reported that they were using CAM. The most commonly used CAM methods were stinging nettle (57%) and prayer and spiritual healing (49%). No relationship was found between the use of CAM and the patient's age, time to diagnosis, cancer stage, chemotherapy use, smoking and residence. However, the analyses showed a positive association between CAM and role functioning (P=0.014) and financial difficulties (P=0.011); and a negative association between CAM and emotional functioning (P=0.033). CONCLUSIONS: Based on the previous studies, 20-83.3% of breast cancer patients among different countries and cultures used CAM. Our results suggested that the use of CAM among women is quite popular, but they showed no correlation between CAM usage and anxiety and depression. In addition, CAM usage was more common in breast cancer patients with a poor emotional and financial status.

Intrapleural hyperthermic perfusion chemotherapy in subjects with metastatic pleural malignancies.

OBJECTIVES: Malignant pleural effusion (MPE) means poor prognosis in the majority of cases. Intrapleural Hyperthermic perfusion chemotherapy (HIPEC) looks promising approach for these patients. We aimed to investigate whether cytoreductive surgery followed by HIPEC provides any survival benefit in cases with metastatic MPEs. METHODS: Between January 2009 and December 2011, 19 patients with metastatic MPEs were treated with HIPEC following surgical interventions such as pleurectomy/decortication and/or lung resection (group 1). Comparison was done with historical control groups consisted of patients who received either talc pleurodesis or pleurectomy/decortication followed by systemic treatment for the management of metastatic MPEs between June 2007 and June 2008 (group 2 and 3). Statistical analyses including overall survival, disease free interval were done for the group comparisons. RESULTS: Median survival in group 1, 2 and 3 were 15.4, 6, 8 months, respectively. One year survival was 54.7% in group 1 where it was 0.6% and 0.8% in group 2 and 3, respectively. There was no operative mortality. Morbidity was occurred in 1 patient in group 1 (5.3%). CONCLUSIONS: HIPEC combined with cytoreductive surgery seems to be a promising treatment option for subjects with metastatic MPEs. Further studies are needed for the optimization of HIPEC method, drug of choice, and the best combination therapy for the multimodal treatment.

Results of adjuvant FOLFOX regimens in stage III colorectal cancer patients: retrospective analysis of 667 patients.

OBJECTIVE: The aim of this study was to assess the use of 5-fluorouracil (5-FU), leucovorin and oxaliplatin (FOLFOX) regimens in clinical practice according to their efficacy and toxicity. METHODS: Patients who received oxaliplatin-containing regimens after curative resection for colorectal carcinoma from 10 different oncology centers between May 2004 and December 2009 were included in the study. All patients were treated with FOLFOX regimens. Patients with rectal carcinoma were also treated with chemoradiotherapy with 5-FU after 2 cycles of a FOLFOX regimen. RESULTS: The median age of the patients was 56 years (range 17-78). Of the total 667 patients, 326 were given FOLFOX-4, 232 were given modified FOLFOX-4 and 109 were given FOLFOX-6. The distribution according to disease stage was 33 patients with stage IIIA colorectal cancer, 382 patients with stage IIIB and 252 patients with stage IIIC. The most common adverse events were neutropenia (54%), nausea (36.9%), neuropathy (38.2%) and anemia (33.1%) for all grades. The median follow-up time was 23 months (range 1-79). Three-year disease-free survival and overall survival were 65 and 85.7%, respectively. CONCLUSION: The different oxaliplatin-containing 5-FU-based adjuvant chemotherapy regimens in patients with stage III colorectal cancer seemed to be at least equal in terms of efficacy regardless of the method of 5-FU administration or oxaliplatin dose.

Leech therapy for symptomatic relief of cancer pain.

OBJECTIVE: Most patients with advanced stage cancer report moderate to severe pain. The leech (Hirudo medicinalis) is commonly used in traditional medicine for relief of localized pain. DESIGN: We report a case of severe pain related to advanced stage cancer successfully treated by self-applied leeches. SETTING AND PATIENTS: A 62-year-old male patient with synchronous renal cell carcinoma and leiomyosarcoma was admitted with severe pain in the lumbar region. The pain was refractory to radiotherapy, and systemic and epidural analgesic infusion. RESULTS: Two months the patient came to the clinic in good condition free of pain. The patient reported outpatient self-treatment with seven leeches to the lumbar region in the interim that resulted in complete healing of pain. CONCLUSIONS: This is the first report indicating possible activity of leeches in cancer pain.

The use of complementary therapies in cancer patients: a questionnaire-based descriptive survey from southeastern Turkey.

OBJECTIVES: A study was designed to measure the frequency of complementary therapy (CT) usage in cancer patients in southeastern Turkey. The demographic characteristics associated with the use of CT are sought in patients undergoing or following conventional treatment. METHODS: A descriptive survey was performed in a total of 560 cancer patients. Questionnaire-based measures of demographics, expectations, and effects of using different types of CT and perceived benefits were recorded. RESULT: Demographic characteristics (age, gender, education status, etc.) did not differ among CT users and non-CT users. Three hundred ten patients (55.4%) had used at least one type of CT since the time of the initial diagnosis of cancer. The most frequently used CT method was herbal therapy, and the most commonly used herb was the stinging nettle. The source of information about CT was mainly from friends/family, whereas physicians and nurses played a small part in providing CT-related information. The majority of the patients used CT to benefit more from medical treatment. Only 20.7% of the patients considered themselves not benefiting from using CT. CONCLUSIONS: Currently more than half of Turkish patients with cancer use CT in addition to the standard medical approaches. CT usage is not associated with any specific demographic variables. Health professionals should not disregard the reality of CT usage in cancer patients. Because the majority of cancer patients use CT regardless of the medical advice, randomized clinical trials are needed to explore risks and benefits associated with CT modalities in cancer.

Anastrozole-associated sclerosing glomerulonephritis in a patient with breast cancer.

OBJECTIVE: Anastrozole is a selective aromatase inhibitor and is used for the hormonal treatment of postmenopausal breast cancer. There are major side effects of anastrozole including decrease in both lumbar spine and total hip bone mineral density, increase in the incidence of all bone fractures (especially fractures of spine, hip and wrist), joint disorders and increase in the cholesterol level. CASE SUMMARY: We report a case of a 73-year-old postmenopausal woman with stage T2N0M0 breast cancer. Adjuvant chemotherapy was not indicated and anastrozole hormonotherapy was started. Diagnosis of sclerosing glomerulonephritis occurred in this patient during anastrozole use, suggesting a newly defined side effect of anastrozole. DISCUSSION: Renal elimination is not a significant pathway of elimination for anastrozole, clearance of anastrozole is unchanged even in severe renal impairment. Dosing adjustment in patients with renal dysfunction is not necessary for anastrozole. We believe that the acute renal failure in our patient was associated with anastrozole. Renal injury due to anastrozole has not been published in the English literature. CONCLUSIONS: Anastrozole may be the causative factor in patients with sclerosing glomerulonephritis.

Upper and lower gastrointestinal endoscopical investigation in elderly patients with iron deficiency anaemia.

Iron deficiency anaemia is frequently observed in male adults and postmenopausal women due to chronic occult bleeding, usually from the gastrointestinal tract. Practically, as endoscopical investigation of the gastrointestinal system is an invasive procedure, iron replacement treatment was generally started without investigation of the underlying aetiology even in first-line health institutions. This study evaluates the role of endoscopy in the investigation of the aetiology of anaemia in 95 patients (51 males, 44 females), aged 64.9+/-12.5 years (range 50-90 years). All patients having iron deficiency anaemia were investigated by upper gastrointestinal endoscopy and colonoscopy. Upper and lower gastrointestinal pathologies were seen in 10 (10.6%) and 55 (57.8%) patients, respectively. However, no gastrointestinal lesion was found in 30 (31.6%) patients with iron deficiency anaemia. Out of the 95 patients, 16 (16.9%) had erosive gastritis, 15 (15.8%) duodenal ulcer, 8 (8.4%) gastric ulcer, 7 (7.3%) gastric tumours, 7 (7.3%) oesophagitis. 5 (5.4%) colon tumours, 3 (3.2%) haemorrhoids, 2 (2.1%) non-tropical sprue, 1 (1%) colonic polyp, and 1 (1%) colitis. In the majority of elderly patients with iron deficiency anaemia, upper gastrointestinal system disease was found. In 12 (12.7%) patients in the study group, malignancies were detected. In elderly patients with iron deficiency anaemia, the aetiology should be highlighted before giving iron supplementation.
