Real-life data of abiraterone acetate and enzalutamide treatment in post-chemotherapy metastatic castration-resistant prostate cancer in Poland.

Background: Abiraterone acetate (ABI) and Enzalutamide (ENZA) are second-generation hormone drugs that show breakthrough activity in post-chemotherapy, metastatic castration-resistant prostate cancer (mCRPC). The leading oncological and urological guidelines indicate both drugs with the same strong recommendation. There is a lack of randomized trials which compare the efficacy of ABI and ENZA. The current study aimed to compare the effectiveness of the drugs with an analysis of prognostic factors related to those drugs. Patients and methods: The study included 420 patients with docetaxel (DXL) pretreated mCRPC from seven Polish cancer centers. Patients were treated according to inclusion and exclusion criteria in the Polish national drug program (1000 mg ABI and 10 mg prednisone, n=76.2%; ENZA, 160 mg; n=23.8%). The study retrospectively analyzed the overall survival (OS), time to treatment failure (TTF), PSA 50% decline rate (PSA 50%) and selected clinic-pathological data. Results: In the study group, the median OS was 17 months (95% CI: 15.6-18.3). The median OS (26.1 vs. 15.7 mo.; p<0.001), TTF (14.2 vs. 7.6 mo.; p<0.001) and PSA 50% (87.5 vs. 56%; p<0.001) were higher in ENZA than in ABI treatment. Multivariate analysis shows that ENZA treatment and PSA nadir <17.35 ng/mL during or after DXL treatment were related to longer TTF. ENZA treatment, DXL dose ≥750 mg, PSA nadir <17.35 ng/mL during or after DXL treatment was related to longer OS. Conclusions: ENZA treatment may be related to more favorable oncological outcomes than ABI treatment in the studied Polish population of patients. A 50% decline in PSA is an indicator of longer TTF and OS. Due to the non-randomized and retrospective nature of the analysis, the current results require prospective validation.

Long-term clinical evidence of comparable efficacy and toxicity of nivolumab and pembrolizumab in advanced melanoma treatment.

Pembrolizumab and nivolumab (anty-PD-1 antibody) are commonly used for the treatment of melanoma patients. However, their efficacy and safety have never been directly compared, leaving little guidance for clinicians to select the best therapy. The study included patients with inoperable or metastatic melanoma treated in first line with anti-PD-1 immunotherapy (nivolumab or pembrolizumab). In total 1037 patients were enrolled in the study, 455 (44%) patients were treated with pembrolizumab and 582 (56%) with nivolumab. The estimated median overall survival (OS) in the pembrolizumab and nivolumab groups was 17.4 and 20.0 months [ P = 0.2323; hazard ratio (HR), 1.1; 95% confidence interval (CI), 0.94-1.28], respectively, whereas the median progression-free survival (PFS) was 5.6 and 7.5 months ( P = 0.0941; HR, 1.13; 95% CI, 0.98-1.29), respectively. The estimated 2- and 3-year OS in the pembrolizumab and nivolumab groups were 42/34% and 47/37%, respectively, and the PFS was 25/21% and 29/23%, respectively. There were 391 (49%) immune-related adverse events (irAEs) of any grade during treatment, including 133 (42%) related to pembrolizumab treatment and 258 (53%) to nivolumab treatment. A total of 72 (9.6%) irAEs were in G3 or G4, including during pembrolizumab 29 (9%) and nivolumab 48 (11%). There were no differences in OS, PFS and overall response rates between nivolumab and pembrolizumab therapy in previously untreated patients with advanced/metastatic melanoma. There were no differences in the frequency of G1/G2 or G3/G4 irAEs. The choice of treatment should be based on the preferences of the patient and the clinician.

Long-Term Real-World Outcomes and Safety of Vemurafenib and Vemurafenib + Cobimetinib Therapy in Patients with BRAF-Mutated Melanoma.

BACKGROUND: Combined treatment with BRAFi and/or MEK inhibitors (MEKi) improves outcomes in advanced melanoma patients in comparison with monotherapy. OBJECTIVE: We aim to report real-world treatment efficacy and safety of vemurafenib (V) and vemurafenib + cobimetinib (V + C) from 10 years of practice. PATIENTS AND METHODS: A total of 275 consecutive patients with unresectable or metastatic BRAF mutated melanoma started first-line V or V + C treatment between 1 October 2013 and 31 December 2020. Survival analyses were performed using the Kaplan-Meier method, and Log-rank and Chi-square tests were used for comparison between groups. RESULTS: The estimated median overall survival (mOS) was 10.3 months in the V group, and 12.3 months in the V + C group (p = 0.0005; HR = 1.58, 95% CI 1.2-2.1), although the latter group of patients had lactate dehydrogenase elevated numerically more often. Estimated median progression-free survival (mPFS) was 5.5 months in the V group, and 8.3 months in the V + C group (p = 0.0002; HR = 1.62, 95% CI 1.3-2.1). Complete response, partial response, stable disease, and progressive disease as best responses were recorded in the V/V + C groups in 7%/10%, 52%/46%, 26%/28%, and 15%/16% of patients, respectively. The numbers of patients with any grade of adverse effects were similar in both groups. CONCLUSIONS: We confirmed significant improvement in the mOS and mPFS of unresectable and/or metastatic BRAF mutated-melanoma patients treated outside clinical trials with V + C as compared with V, with no major increase in toxicity for the combination.

RET Proto-Oncogene-Not Such an Obvious Starting Point in Cancer Therapy.

Mutations and fusions of RET (rearranged during transfection) gene are detected in a few common types of tumors including thyroid or non-small cells lung cancers. Multiple kinase inhibitors (MKIs) do not show spectacular effectiveness in patients with RET-altered tumors. Hence, recently, two novel RET-specific inhibitors were registered in the US and in Europe. Selpercatinib and pralsetinib showed high efficacy in clinical trials, with fewer adverse effects, in comparison to previously used MKIs. However, the effectiveness of these new drugs may be reduced by the emergence of resistance mutations in RET gene and activation of different activating signaling pathways. This review presents the function of the normal RET receptor, types of molecular disturbances of the RET gene in patients with various cancers, methods of detecting these abnormalities, and the effectiveness of modern anticancer therapies (ranging from immunotherapies, through MKIs, to RET-specific inhibitors).

Long Term Results and Prognostic Biomarkers for Anti-PD1 Immunotherapy Used after BRAFi/MEKi Combination in Advanced Cutaneous Melanoma Patients.

(1) Background: BRAFi/MEKi are usually offered as a first line treatment for patients requiring rapid response; with elevated lactate dehydrogenase (LDH) activity, large tumor burden, and with brain metastases. The efficacy of second line therapies after BRAFi/MEKI failure is now well defined. (2) Methods: Patients treated with first line target BRAFi/MEKi therapy (vemurafenib plus cobimetinib, dabrafenib plus trametinib or encorafenib plus binimetinib); and for the second line treatment immunotherapy with programmed cell death 1 (PD-1) checkpoint inhibitors (nivolumab or pembrolizumab) with at least one cycle of second line were analyzed for survival and prognostic biomarkers. (3) Results: There were no statistically significant differences in ORR between the treatment groups with nivolumab and pembrolizumab, as well as median progression free-survival (PSF) and overall survival (OS) since the initiation of second line therapy; on nivolumab OS was 6.6 months, and on pembrolizumab 5.0 months. The greatest clinical benefit with second line immunotherapy was observed in patients with LDH ≤ ULN and <3 organ sites with metastasis at baseline. Longer OS was also noted in patients with time to PD >6 months in first line (slow progression). (4) Conclusions: Second line anti-PD1 immunotherapy is effective in BRAF-mutated melanoma patients after BRAFi/MEKi therapy failure.

Development of immunity-related adverse events correlates with baseline clinical factors, survival and response to anti-PD-1 treatment in patients with inoperable or metastatic melanoma.

BACKGROUND: The relationship between immune related adverse events (irAEs) and efficacy is not definitively proven, and data on the relationship between irAE and treatment efficacy are contradictory. MATERIAL AND METHODS: Five hundred ninety-three consecutive patients with unresectable or metastatic melanoma treated in the first line with anti-PD-1 (nivolumab or pembrolizumab) between January 2016 and December 2019 were enrolled in the study. RESULTS: Statistically significant differences were demonstrated between the group of patients without and with irAE in median OS and PFS (p < .0001 both) and also in OS between the group of patients without irAE and patients with irAE within 3, 6, and 9 months from the start of anti-PD-1 therapy (p = .0121, p = .0014, p < .0001; respectively) and PFS (p = .0369, p = .0052, p = .0001; respectively). A statistically significant relationship was demonstrated between the occurrence of irAE and the location of the primary tumor (skin vs. mucosa vs. unknown; p = .0183), brain metastasis (present vs. absent; p = .0032), other locations (present vs. absent, p = .0032), LDH (normal vs. elevated; p = .0046) and stage according to TNM (p = .0093). CONCLUSION: The occurrence of irAE was associated with longer OS, PFS, and more frequent response to treatment. IrAE occurred statistically significantly more often in patients with mucosa primary tumor, with normal LDH levels, without brain metastases, stages III, M1a, and M1b.

Impact of copy number variant and single nucleotide polymorphism of the programmed death-ligand 1 gene, programmed death-ligand 1 protein expression and therapy regimens on overall survival in a large group of Caucasian patients with non-small cell lung carcinoma.

Anti-programmed death-1 or anti-programmed death-ligand 1 (PD-L1) blockade may be ineffective in some patients with non-small cell lung cancer (NSCLC) with high percentage of tumor cells with PD-L1 expression. In addition, immunotherapy may provide great benefits in patients without PD-L1 expression. The present study assessed PD-L1 protein expression by immunohistochemistry, copy number variation (CNV) of PD-L1 and two single nucleotide polymorphisms (SNPs), rs822335 and rs822336, in the promoter of PD-L1 by quantitative PCR in 673 patients with NSCLC. Overall survival time of patients with NSCLC depending on the assessed predictive factors (PD-L1 CNV or SNP) and the treatment methods (immunotherapy in first/second line of treatment or chemotherapy) was analyzed. The present study revealed significantly higher PD-L1 copies number in patients with ≥10% and ≥50% of tumor cells with PD-L1 expression compared to patients with lower percentage of PD-L1-positive tumor cells (P=0.02 and P=0.0002, respectively). There was a significant positive correlation (R=0.2; P=0.01) between number of PD-L1 copies and percentage of tumor cells with PD-L1 protein expression. Percentage of tumor cells with PD-L1 expression was lower in patients with TT genotype of the rs822335 polymorphism compared to those with CC genotype (P=0.03). The present study observed significantly higher risk of death in patients treated with chemotherapy compared to those treated with immunotherapy (P<0.0001; hazard ratio=2.4768; 95% confidence interval, 2.0120-3.0490). The present study demonstrated a close relationship between PD-L1 copies number, genotype of rs822335 PD-L1 polymorphism and PD-L1 protein expression on tumor cells. However, the impact of CNV and SNPs of PD-L1 on overall survival of patients with NSCLC requires further investigation.

Anti-programmed cell death-1 therapy in octogenarian and nonagenarian advanced/metastatic melanoma patients.

Immunotherapy with anti-programmed cell death-1 (PD-1) agents is an effective treatment for metastatic melanoma. Octogenarians and nonagenarians represent a significant cohort of melanoma patients. This multicenter retrospective analysis enrolled 499 patients treated with nivolumab or pembrolizumab. Seventy-three patients were aged 80-100, 218 patients were aged 65-79, and 208 patients were <65 years old. Baseline parameters were comparable. The median overall survival (OS) was 14.7, 18.7, 25.9, and the median progression-free survival (PFS) was 8.7, 7.7, and 6.2 months in the age groups of 80-100, 65-79, and <65 years, respectively. The median melanoma-specific survival (MSS) was 22.5, 27.8, and 31.6 months in the age groups of 80-100, 65-79, and <65 years, respectively. There was no statistically significant difference in OS (P = 0.2897), PFS (P = 0.7155), and MSS (P = 0.9235) between the group of 80-100 years old vs. 65-79 and vs. <65 years old patients. Overall response rate and disease control rate was similar in all groups (P = 0.06974 and P = 0.89435, respectively). Overall, the immune-related adverse event (irAE) rate was comparable in the three age groups (41, 34, and 37.5% in the groups of patients aged 80-100, 65-79, and <65 years, respectively). Also, the rates of G3 and G4 irAEs were comparable (4, 6, and 7% in the groups of patients, respectively). The efficacy and toxicity of anti-PD-1 therapy in octogenarians and nonagenarians with metastatic melanoma are similar as in patients aged <65 years and 65-79 years. The patients' age should not be considered as an exclusion criterion for anti-PD-1 treatment.

First-line treatment of advanced/metastatic melanoma with anti-PD-1 antibodies: multicenter experience in Poland.

Aim: To evaluate treatment results in advanced/metastatic melanoma patients treated with anti-PD-1 immunotherapy in routine practice in oncology centers in Poland. Methods: Multicenter retrospective analysis included 499 patients with unresectable/metastatic (stage IIIC-IV) melanoma treated with anti-PD-1 in first-line therapy. Results: Estimated median overall survival (OS) and progression-free survival (PFS) were 19.9 and 7.9 months, respectively. Multivariate analysis confirmed that ECOG 0, no brain metastases, normal lactate dehydrogenase level and occurrence of immune-related adverse events (irAEs) were statistically significantly associated with improved OS and PFS. Any irAE occurred in 24% of patients. Grade 3 or Grade 4 irAEs occurred in 6% of patients. Conclusion: Analysis revealed a slightly worse OS in real-world treatment in comparison to clinical trials (KEYNOTE-006 and CheckMate 066). Polish population treatment results are similar to other studies of real-world data. PFS and ORR are similar in our research and clinical trials.

Lung Cancer Immunotherapy in Transplant Patients and in Patients With Autoimmune Diseases.

The use of immune checkpoint inhibitors (ICIs) delivered great and new possibilities in modern treatment of many types of cancers. This therapy based on blockade of such molecules as CTLA-4 (cytotoxic T lymphocyte-associated antigen), PD-1 (programmed cell death receptor type 1), or PD-1 ligand (PD-L1) brings a new hope for patients with non-small cell lung cancer (NSCLC), melanoma, or head and neck squamous carcinoma. Efficacy of immunotherapy was proven in many clinical trials. Unfortunately, ICIs treatment was not addressed to the patients with preexisting allogeneic transplants or autoimmune diseases mainly due to high risk of transplant rejection, exacerbation of autoimmune diseases, and risk of serious toxicity. However, it is possible to receive anti-tumor response to ICIs treatment avoiding graft rejection by adjusting the immunosuppression. Obviously, it depends on the type of transplants: the use of immunotherapy is usually possible in kidney or corneal recipients, but it could be difficult in patients with liver and heart transplant. Therefore, the development of biomarkers for tumor response and transplant rejection in ICIs treated patients is essential. Data coming from published literature support the possibilities of using ICIs in patients with preexisting autoimmune diseases who undergoing proper management of side effects of immunotherapy or when the potential benefits of such treatment outweigh the potential risks. This depends on the type of autoimmune disease and may be difficult or not feasible in patients with systemic lupus erythematosus or systemic sclerosis. Therefore, it may be appropriate to include cancer patients with preexisting autoimmune disease or with allogeneic transplants in clinical trials using immunotherapy when no other effective cancer treatment options exist.

Imperfect Predictors for Lung Cancer Immunotherapy-A Field for Further Research.

The armamentarium for lung cancer immunotherapy has been strengthened using two groups of monoclonal antibodies: 1) anti-PD-1 antibodies, including pembrolizumab and nivolumab, which block the programmed death 1 receptor on the lymphocyte surface, resulting in increasing activity of these cells, and 2) anti-PD-L1 antibodies, including atezolizumab, durvalumab, and avelumab, which block the ligand for the PD-1 molecule on tumor cells and on tumor-infiltrating immune cells. The effectiveness of both groups of antibodies has been proven in many clinical trials, which translates into positive immunotherapeutic registrations for cancer patients. Regarding the predictive factor, PD-L1 expression on cancer cells is the only biomarker validated in prospective clinical trials used for qualification to immunotherapy in advanced non-small cell lung cancer (NSCLC) patients. However, it is not an ideal one. Unfortunately, no clinical benefits could be noted in patients with high PD-L1 expression on tumor cells against the effectiveness of immunotherapy that may be observed in patients without PD-L1 expression. Furthermore, the mechanism of antitumor immune response is extremely complex, multistage, and depends on many factors. Cancer cells could be recognized by the immune system, provided tumor-specific antigen presentation, and these arise as a result of somatic mutations in tumor cells. Based on novel immunotherapy registration, high tumor mutation burden (TMB) has become an important predictive factor. The intensity of lymphocyte infiltration in tumor tissue may be another predictive factor. The effectiveness of anti-PD-L1 immunotherapy is observed in patients with high expression of genes associated with the effector function of T lymphocytes (i.e., their ability to produce IFN-gamma). This does not end the list of potential factors that become useful in qualification of cancer patients for immunotherapy. There remains a need to search for new and perfect predictive factors for immunotherapy.

BRAF and MEK inhibitors rechallenge as effective treatment for patients with metastatic melanoma.

Despite considerable progress made in the treatment of patients with advanced melanoma, the majority of the patients treated with BRAF and mitogen-activated protein inhibitors (BRAFi and MEKi) experience a disease progression due to acquired resistance. Currently, ongoing studies explore the possibility to overcome or reverse this process. Our multicenter retrospective analysis included 51 patients with metastatic BRAF-mutated melanoma who had previously progressed on BRAFi/MEKi than had progressed on immunotherapy (anti-progression disease-1 or anti-cytotoxic T-lymphocyte-associated protein 4) and next were rechallenged with BRAFi/MEKi. Median age at BRAFi/MEKi rechallenge was 56 (range: 31-82 y/o). Median overall survival from the start of the first BRAFi/MEKi therapy and from rechallenge BRAFi/MEKi treatment was 29.7 and 9.3 months, respectively, whereas median progression-free survival was 10.5 and 5.9 months, respectively. Six-month, annual, and 2-year overall survival rates on both treatments were: 98% and 55%, 92% and 29%, and 69% and 2%, respectively. A response rate to treatment was higher in the group receiving BRAFi/MEKi for the first time as compared with the group receiving BRAFi/MEKi rechallenge and was overall response rate 72% and 27%; disease control rate 92% and 63%. Time interval between the end of the first BRAFi/MEKi treatment and the beginning of BRAFi/MEKi rechallenge did not influence median overall survival or progression-free survival. A lower toxicity rate was noted with BRAFi/MEKi rechallenge. BRAFi/MEKi rechallenge treatment remains clinically important and is associated with the lower toxicity. BRAFi/MEKi rechallenge efficacy is higher in patients who are in good performance status, with normal lactate dehydrogenase, and without brain metastases.

Tissue MicroRNA Expression as a Predictor of Response to Immunotherapy in NSCLC Patients.

INTRODUCTION: Expression of PD-L1 protein on tumor cells, which is so far the only validated predictive factor for immunotherapy, is regulated by epigenetic and genetic factors. Among the most important ones that regulate gene expression are microRNAs. MATERIALS AND METHODS: The study included 60 patients with NSCLC who underwent first or second line immunotherapy with pembrolizumab or nivolumab. FFPE materials were collected before the start of immunotherapy. We examined relative expression of microRNAs (miR-141, miR-200a, miR-200b, miR-200c, miR-429, miR-508-3p, miR-1184, miR-1255a) and PD-L1 mRNA expression. Copy number variation (CNV) of PD-L1 gene by qPCR and FISH methods were assessed. Two single nucleotide polymorphisms (SNPs) in promoter region of PD-L1 gene (rs822335 and rs822336) were examined. Expression of PD-L1 protein on tumor cells was assessed by immunohistochemistry (IHC). The response rate to immunotherapy and progression free survival (PFS) measured in weeks and overall survival (OS) measured in months from the start of immunotherapy were evaluated. RESULTS: Response to immunotherapy was observed in nine patients (15%, including one complete response), disease stabilization in 22 patients (36.7%), and progression in 29 patients (48.3%). Significantly higher (p=0.015) expression of miR-200b and significantly lower (p=0.043) expression of miR-429 were observed in responders compared to patients who did not respond to immunotherapy. The median PFS in the whole group of patients was 16 weeks, and the median OS was 10.5 month. In univariate analysis, the median PFS was significantly higher in patients with high miR-200b expression (HR=0.4253, 95%CI: 0.1737-1.0417, p=0.05) and high miR-508 expression (HR=0.4401, 95%CI: 0.1903-1.0178, p=0.05) and with low expression of miR-429 (HR=0.1288, 95%CI: 0.01727-0.9606, p=0.0456) compared to patients with low and high expression of these molecules, respectively. The median OS was higher in patients with low expression of miR-429 (HR=0,6288, 95%CI: 0,3053-1,2949, p=0.06) compared with patients with high expression of this microRNA. In multivariate analysis, we found that patients with PD-L1 expression on ≥1% of tumor cells compared to patients without PD-L1 expression on cancer cells had a significantly lower risk of progression (HR=0.3857, 95%CI: 0.1612-0.9226, p=0.0323) and death (HR=0.377, 95%CI: 0.1636-0.8688, p=0.022). CONCLUSION: The miR-200b and miR-429 molecules in tumor cells seem to have greatest impact on the effectiveness of immunotherapy in NSCLC patients.

Blast from the past: Perioperative use of the Maruyama computer program for prediction of lymph node involvement in the surgical treatment of gastric cancer following neoadjuvant chemotherapy.

BACKGROUND: Surgical quality assurance is a key element of gastric cancer treatment. The Maruyama Computer Program (MCP) allows to predict lymph node involvement in stations no. 1-16. The aim of the current study was to evaluate the accuracy of the MCP predictions in GC patients treated with neoadjuvant chemotherapy (nCTH) followed by gastrectomy with adequate lymphadenectomy. METHODS: 101 patients who underwent preoperative nCTH followed by D2 gastrectomy with curative intent were analysed. The response to nCTH was measured using the tumour regression grade system. RESULTS: Test sensitivity, specificity, PPV, NPV and accuracy of the MCP were 92%, 33%, 41%, 89%, and 53%, respectively. In patients with response to nCTH, number of false positive (FP) results was significantly higher than in patients who did not respond to nCTH both in the N1 (56.3% vs 28.9%, p < 0.0001) and in the N2 (59% vs 41%, p < 0.0001) trier. The risk for FP results was 6 times higher in N1 (OR = 6.50, 95%CI: 3.91-10.82,; p < 0.0001) and N2 (OR = 5.84, 95%CI: 2.85-11.96; p < 0.0001) triers. In patients with intestinal type GC, the risk for FP results was 4 times higher than in other histologic types of GC in both N1 (OR = 4.23, 95%CI: 2.58-6.95; p < 0.0001) and N2 (OR = 4.23, 95%CI: 2.02-9.62; p = 0.0002) triers. CONCLUSIONS: MCP predictions in the GC patients treated with nCTH have low specificity due to significantly high number of FP results. Noticeably low accuracy level of predictions indicate a need for new prediction models, based on Laurén classification, since it may provide some information on expected regression grade.

Place of residence does not significantly influence radiological morphology of cervical cancer.

INTRODUCTION AND OBJECTIVE: Cervical squamous cell carcinoma is one of the most common malignancies of women. Its incidence and morphology was analyzed based on the magnetic resonance (MR) data among rural and urban residents. MATERIAL AND METHODS: The study involved 61 Caucasian women (58.26±9.63 years) preliminary diagnosed with a cervical cancer without any previous treatment. Standard MR examination, including diffusion weighted imagining, apparent diffusion coefficient (ADC) value measurement and dynamic contrast enhancement, was performed. RESULTS: The rural residents (n=22) were insignificantly older. Their first and last menstruation were observed later and number of pregnancy was higher than in urban women (n=39). However, the incidence of miscarriage was insignificantly rarer. All the tumour linear diameters as well as its volume were insignificantly higher in rural women. The ADC value of the cervical tumor was insignificantly lower, while ADC of lymphatic nodules was higher in rural women. Insignificant changes in tumour grade between both examined groups were found in histological, clinical and radiological examinations. Place of residence did not influence any clinical symptoms nor tumour volume and its ADC. Colporrhoea and colpodynia were insignificantly more often observed in urban women, while parametrium, urinary bladder and rectal infiltrations were more commonly seen in rural residents. Higher risk of lymphatic spread to the internal iliac and parametral lymphatic nodes was reporte[b]d in the rural community. CONCLUSIONS: Cervical cancer had similar morphology and growth pattern, regardless of the place of residence. However, a insignificantly larger tumour size among rural residents may suggest a higher incidence of lymphatic spread, probably as a result of less aaccess to modern health care.

Life quality of women with breast cancer after mastectomy or breast conserving therapy treated with adjuvant chemotherapy.

INTRODUCTION: Breast cancer is the most frequent malignant neoplasm in women. The evaluation of the quality of life has become a treatment parameter as important as survival. OBJECTIVE: The aim of the study was evaluation of the quality of life among women treated for breast cancer who underwent surgical procedures using two alternative methods: mastectomy or breast conserving therapy (BCT). MATERIALS AND METHOD: 85 patients treated with BCT and 94 patients who underwent mastectomy were evaluated. Standard questionnaires for the evaluation of the quality of life of cancer patients were used - QLQ-C30 (Quality of life questionnaire - core 30) with QLQ-BR23 (Breast Cancer Module). The Hospital Anxiety and Depression Scale was also applied. RESULTS: Social and demographic factors (age, education, marital status) influenced the evaluation of the life quality among both groups. Obtained data was also dependent on the type of surgical procedure and chemical treatment. The level of anxiety and depression also influenced the general quality of life and was higher in women who underwent mastectomy. CONCLUSIONS: Quality of life plays an important role in the treatment process. Women after BCT declared a higher quality of life compared to patients after mastectomy. The process of making the decision concerning the planned surgical procedure should take into consideration the influence of the intervention on the quality of patients' future life.

Evaluation of symptoms of anxiety and depression in women with breast cancer after breast amputation or conservation treated with adjuvant chemotherapy.

OBJECTIVE: Evaluation of the presence of symptoms of anxiety and depression in women treated for breast cancer who underwent surgical procedure using one of two alternative methods, either radical mastectomy or breast conserving treatment (BCT). METHODS: A questionnaire survey involved 85 patients treated in a conservative way and 94 patients after breast amputation. Hospital Anxiety and Depression Scale (HADS), Beck Depression Inventory (BDI) and depression degree evaluation questionnaire were used in the study. The patients' esponses were statistically analyzed. RESULTS: Based on the HADS questionnaire, the total anxiety level in the group of women treated with BCT was 6.96 points, while in the group of patients who had undergone mastectomy the value was 7.8 points. The observed results were statistically significant. In the case of depression, the following values were found: patients after amputation had 8.04 scale value points, and those after BCT had 6.8 scale value points. The observed differences were statistically significant. Negative correlation was found between the level of anxiety and depression. The total level of depression evaluated using the Beck scale was 16.3 points in the BCT group, which means that they suffered from mild depression, while in the mastectomy group the level was 19.6 points, which corresponds to moderate depression. CONCLUSIONS: The level of anxiety and depression among women with breast cancer was influenced by the type of the applied surgical procedure and adjuvant chemotherapy. Demographic variables did not influence the level of anxiety and depression.

[Dural metastatic infiltration in prostate cancer--case report]. / Przerzuty raka gruczolu krokowego do opon mózgowych--opis przypadku.

Metastatic changes secondary to prostate cancer usually occur in bones, less commonly in pelvic lymph nodes, liver, lungs, urinary balder and brain. Less common localization includes skin, testis and other structures. The current paper reports a rare case of metastatic infiltration of the dura mater in patient with prostate cancer (Gleason 8 (4+4)) with disseminated bone metastasis. Magnetic resonance imaging revealed an advance infiltration of dura mater of anterior and posterior cranial fossa without any neoplasmatic-related changes in brain. Along optic nerves it penetrated to the optic canal and right orbit.

Quality of life and occurrence of depression under chemotherapy in patients suffering from lung carcinoma.

INTRODUCTION AND OBJECTIVE: In Poland, lung carcinoma is the most frequent malignant neoplasm in men and the third most frequent in women. The neoplastic disease causes enormous psychic stress and may lead to depressive reactions. The purpose of this research was to assess the quality of life and the occurrence of depression in patients suffering from lung neoplasms and undergoing chemotherapy. MATERIALS AND METHOD: The research covered 102 patients (test group TG) with lung carcinoma and undergoing chemotherapy. In the research, standardised questionnaires: EORTC-QLQ-C30, Beck Depression Inventory and a matrix developed by the researcher were applied. The control group (CG) consisted of 60 healthy people who were examined by the Beck Depression Inventory. RESULTS: A highly statistically significant dependency was found (p<0.01) between the general quality of life and the occurrence of depression. 51.5% of those examined with a very low level of general quality of life had the symptoms of severe depression. Those examined who had a very high level of general quality of life did not have features of severe depression. A statistically significant dependency (p<0.01) was ascertained between the occurrence of depression and the health condition of those examined. CONCLUSIONS: Depression symptoms occur more frequently and with greater intensity in patients suffering from lung neoplasm, compared to the group of healthy people (p<0.01). A statistically significant connection between marital status, place of residence, and assessment of quality of life was found out (p<0.05).
