Image-guided high-dose-rate brachytherapy as the method of choice in medically inoperable early-stage endometrial cancer patients.

PURPOSE: About 3-9% of patients with endometrial cancer are unable to undergo surgery due to medical comorbidities, including morbid obesity, or age-related frailty syndrome. An alternative curative option is irradiation. The aim of this prospective study was to evaluate clinical outcomes of high-dose-rate intracavitary brachytherapy (HDR-ICBT) treatment in such patients. MATERIALS AND METHODS: Seventy-eight patients with FIGO stage I-II endometrial cancer disqualified from surgery were treated with HDR-ICBT with 45-52,5 Gy prescribed to high-risk clinical target volume (HR-CTV) in 5-9 fractions given once a week. All fractions were planned using computed tomography (CT) scans. RESULTS: The median follow-up time was 67 months. Median age was 79 years (range: 42-93 years). Median body mass index (BMI) was 39,1 kg/m2 (range: 24,2-68 kg/m2). We observed no statistically significant impact of BMI ≥ 40 on overall survival (OS) or prgression free survival (PFS). The 3- and 5-year OS for the whole population were 69% and 55%, respectively. The impact of high risk features (FIGO II, grade 3 or type 2 cancer) on OS was significant (p = 0,049). The 5-year cumulative incidence of local failure, distant metastases and non-cancer death were 12,9% [95% CI: 5,4%-20,5%], 6,4% [95% CI: 0,9%-11,9%], 33,1% [95% CI: 22,3%-43,9%], respectively. The 5-year risk of cancer and non-cancer death were 9% (95% CI: 3%-16%) and 36% (95% CI: 25%-47%), respectively. We observed G1 vaginal apex stenosis only. CONCLUSIONS: CT-guided HDR-ICBT is a feasible and safe management of FIGO stage I endometrial cancer in obese and elderly patients. The survival outcome of the treated group is influenced more by associated comorbidities than by the progression of endometrial cancer.

Safety and efficacy of induction immunochemotherapy with rituximab, methotrexate, ifosfamide, and vincristine (R-MIV) in patients with primary CNS lymphoma including recent COVID-19 pandemic experience.

Clinical data on primary central nervous system (CNS) lymphoma (PCNSL) patients is mostly generated from prospective studies, and many frail real-world patients are not included. Recently,the diagnosis and treatment of PCNSL patients was confounded by the COVID-19 pandemic. In particular, treatment with high-dose cytarabine was linked to increased risk of pneumonia and virus persistence. We report on outcome of the induction regimen R-MIV (rituximab, methotrexate, ifosfamide, and vincristine) involving intensive administration of high-dose methotrexate (3.5 g/m2 ) with ifosfamide, every 2 weeks and rituximab once per week for six doses. The median age and performance status (PS) for 64 patients was 58 years and 2 (PS 3; 22%) respectively. The overall response rate by magnetic resonance imaging/computed tomography (MRI/CT) was 73% (n = 46/63), with an additional 17.5% (n = 11/63) patients without measurable disease at baseline. Grade 3-4 haematological toxicity was low for R-MIV (neutropenia: 25% and thrombocytopenia: 1%). Three patients (4.7%) died from treatment-related toxicity. Co-existence of SARS-CoV-2 infection with cytomegalovirus reactivation and the varicella-zoster virus in two patients was fatal. Fifty patients (78%) were eligible for consolidation. Median progression-free and overall survival were not reached (median follow-up: 44 months). In conclusion, the R-MIV regimen is feasible in routine practice, effective and safe, even during the COVID-19 pandemic.

Prognostic value of pan-immune-inflammation value and body mass index in geriatric patients with metastatic renal cell carcinoma treated with tyrosine kinase inhibitors as first line treatment. A single-center retrospective study.

Introduction: Geriatric patients with metastatic renal cell carcinoma (mRCC) are underrepresented in clinical trials. Evaluation of the efficacy of the treatment and assignation of individuals to proper prognostic groups is an absolute necessity to guarantee them the best possible care. Material and methods: A total of 138 geriatric patients with mRCC treated with first-line tyrosine kinase inhibitors (TKIs) at the Maria Sklodowska-Curie National Research Institute of Oncology were retrospectively analyzed to determine whether the body mass index (BMI) and pan-immune-inflammation value (PIV) are prognostic values for overall survival (OS) and progression-free survival (PFS) in this type of cancer. For this purpose, Cox's proportional hazard model was used. Results: The median duration of follow-up for surviving patients was 46.6 (95% CI: 17.4-75.8) months. The median OS and PFS were respectively 33.8 months (95% CI: 23.8-47.8) and 19.1 months (95% CI: 15.0-23.3). BMI (p = 0.034) and PIV (p < 0.001) were statistically significantly associated with OS, and PIV (p = 0.001) was statistically significantly associated with PFS. The risk of death for patients from the high-PIV group (cut-off point: 548) was 3.4 times higher than for those with lower PIV values. The corresponding risk of progression for patients from the high-PIV group was 2.2 times higher. The G8 geriatric screening tool was not identified as a prognostic factor. Conclusions: Lower PIV and obesity are associated with longer OS in geriatric mRCC patients treated with TKIs in the first line. These factors may be considered while making treatment decisions if further studies show the same results.

Ofatumumab with iphosphamide, etoposide and cytarabine for patients with transplantation-ineligible relapsed and refractory diffuse large B-cell lymphoma.

The efficacy of salvage treatment of diffuse large B-cell lymphoma (DLBCL) patients who relapse or progress (rrDLBCL) after initial therapy is limited. Efficacy and safety of ofatumumab with iphosphamide, etoposide and cytarabine (O-IVAC) was evaluated in a single-arm study. Dosing was modified for elderly patients. Patients received up to six cycles of treatment. The primary end-point was the overall response rate (ORR). Patients were evaluated every two cycles and then six and 12 months after treatment. Other end-points included progression-free survival (PFS), event-free survival (EFS), overall survival (OS) and safety. Seventy-seven patients received salvage treatment with O-IVAC. The average age was 56.8 years; 39% had an Eastern Cooperative Oncology Group (ECOG) performance status of at least 3; 78% had disease of Ann Arbor stage 3 or 4; 58% received one or more prior salvage therapies. The ORR for O-IVAC was 54.5%. The median duration of study follow-up was 70 months. The median PFS and EFS were 16.3 months each. The median OS was 22.7 months. Age, ECOG performance status and the number of prior therapy lines were independent predictors of survival. Treatment-related mortality was 15.5%. O-IVAC showed a high response rate in a difficult-to-treat population and is an attractive treatment to bridge to potentially curative therapies.

First-line R-CVP versus R-CHOP induction immunochemotherapy for indolent lymphoma with rituximab maintenance. A multicentre, phase III randomized study by the Polish Lymphoma Research Group PLRG4.

R-CVP (cyclophosphamide, vincristine, prednisone) and R-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone + rituximab) are immunochemotherapy regimens frequently used for remission induction of indolent non-Hodgkin lymphomas (iNHLs). Rituximab maintenance (RM) significantly improves progression-free survival (PFS) in patients with complete/partial remission (CR/PR). Here we report the final results of a randomized study comparing R-CVP to R-CHOP both followed by RM. Untreated patients in need of systemic therapy with symptomatic and progressive iNHLs including follicular (FL) and marginal zone lymphoma (MZL), mucosa-associated lymphoid tissue (MALT), small lymphocytic (SLL), and lymphoplasmacytic (LPL) lymphoma were eligible. Patients were randomized to receive R-CVP or R-CHOP for eight cycles or until complete response (CR). All patients with CR/PR (partial response) received RM 375 mg/m2 q 2 months for 12 cycles. Primary endpoint was event-free survival (EFS). Two-hundred and fifty patients [FL 42%, MZL/MALT 38%, LPL/ Waldenström Macroglobulinaemia (WM) 11%, SLL 9%] were enrolled and randomized (R-CHOP: 127, R-CVP: 123). Median age was 56 years (21-85), 44% were male, 90% were in stage III-IV, 43% of FL patients had a Follicular Lymphoma International Prognostic Index (FLIPI) score ≥3, and 33·4% of all patients had an IPI score ≥3. At the end of induction treatment, the CR/PR rate was 43·6/50·9% and 36·3/60·8% in the R-CHOP and R-CVP groups (P = 0·218) respectively. After a median follow-up of 67, 66, and 70 months, five-year EFS was 61% vs. 56% (not significant), progression-free survival (PFS) was 71% vs. 69% (not significant) and overall survival (OS) was 84% vs. 89% in the R-CHOP vs. the R-CVP arm respectively. Grade III/IV adverse events (65 vs. 22) occurred in 40 (33·1%) and 18 (15·3%) patients, P = 0·001; neutropenia in 16 (11·6%) and 4 (3·4%) patients, P = 0·017; infection in 14 (10·7%) and 3 (2·5%) patients,; P = 0·011; and a second neoplasm in three versus seven patients., in the R-CHOP and the R-CVP groups respectively. This multicentre randomized study with >five-year follow-up shows similar outcome in patients with indolent lymphoma in need of systemic therapy treated with R-CVP or R-CHOP immunochemotherapy and rituximab maintenance in both arms. The minor toxicity of the R-CVP regimen makes it a reasonable choice for induction treatment, leaving other active agents like doxorubicin or bendamustin for second-line therapy.

Neoadjuvant chemotherapy with or without oxaliplatin after short-course radiotherapy in high-risk rectal cancer: A subgroup analysis from a prospective study.

AIM: To evaluate the role of oxaliplatin in neoadjuvant chemotherapy delivered after short-course irradiation. BACKGROUND: Using oxaliplatin in the above setting is uncertain. PATIENTS AND METHODS: A subgroup of 136 patients managed by short-course radiotherapy and 3 cycles of consolidation chemotherapy within the framework of a randomised study was included in this post-hoc analysis. Sixty-seven patients received FOLFOX4 (oxaliplatin group) while oxaliplatin was omitted in the second period of accrual in 69 patients because of protocol amendment (fluorouracil-only group). RESULTS: Grade 3+ acute toxicity from neoadjuvant treatment was observed in 30% of patients in the oxaliplatin group vs. 16% in the fluorouracil-only group (p = 0.053). The corresponding proportions of patients having radical surgery or achieving complete pathological response were 72% vs. 77% (odds ratio [OR] = 0.88; 95% confidence interval [CI]: 0.39-1.98; p = 0.75) and 15% vs. 7% (OR = 2.25; 95% CI: 0.83-6.94; p = 0.16), respectively. The long-term outcomes were similar in the two groups. Overall and disease-free survival rates at 5 years were 63% vs. 56% (p = 0.78) and 49% vs. 44% (p = 0.59), respectively. The corresponding numbers for cumulative incidence of local failure or distant metastases were 33% vs. 38% (hazard ratio [HR] = 0.89; 95% CI: 0.52-1.52; p = 0.68) and 33% vs. 33% (HR = 0.78; 95% CI: 0.43-1.40; p = 0.41), respectively. CONCLUSION: Our findings do not support adding oxaliplatin to three cycles of chemotherapy delivered after short-course irradiation.

Determinants of prolonged survival for breast cancer patient groups with leptomeningeal metastasis (LM).

The study aimed to assess factors affecting survival of breast cancer patients suffering leptomeningeal metastasis (LM) and to compare survivals in patients with LM as the first and only site of metastases at presentation to patients with LM and metastases in other organs, along with selecting a patient group which had the best survival outcomes. Subject groups consisted of 187 patients consecutively referred during 1999-2015. A Cox proportional hazards model was used to identify factors associated with prolonged survival from LM. The Cox prognostic index was created to identify the group of patients with the most favorable prognosis. Median survival for all patients and for those with LM as the first site of metastases at presentation was 17 weeks and 1 year-survival was 15 and 16%, respectively. Factors beneficially affecting survival were: KPS ≥ 70, older age, biological subtype ER/PR+HER2-, systemic treatment, intrathecal treatment and radiation therapy. Based on these factors, 4 prognostic groups were found, with the most favorable group being 24 LM patients with median survival of 9.6 months. In this group, all patients were treated systemically and all were irradiated, 88% had KPS ≥ 70, about 80% had luminal breast cancer, 75% were treated intrathecally and 58% were more than 53 years old. Out of 4 prognostic groups of patients with LM, the most favorable group was selected. The median survival of breast cancer patients with the leptomeninges as the only site of metastases was comparable to those who had metastases in the leptomeninges and in other organs.

Serous Carcinoma of the Uterine Cervix, an Extremely Rare Aggressive Entity: A Literature Review.

BACKGROUND/AIMS: Serous carcinoma of the uterine cervix (USCC) is an extremely rare subtype. To establish the treatment strategy in patients with USCC is an important issue. METHODS: MEDLINE (PubMed) was searched for all articles published after the first publication by Lurie et al. [Eur J Obstet Gynecol Reprod Biol 1991; 40: 79-81], reporting woman diagnosed with USCC. Because of limited numbers of studies on the topic of the study, we could not keep a restriction of eliminating smaller sample sizes. RESULTS: A search of PubMed demonstrated that 113 cases of USCC have been reported in the literature since the first publication. The current treatment modality adopted for early cervical cancer is hysterectomy with bilateral iliac-obturator lymphadenectomy and postoperative radiotherapy (RT) or radiochemotherapy (RT-CT) if risk factors for cervical carcinoma appear. The treatment strategy for locally advanced USCC is preoperative RT-CT or chemotherapy (CHTH) with the intention to treat the patient surgically. The treatment option for disseminated disease is CHTH with paclitaxel and carboplatin. CONCLUSION: Risk factors and a more advanced clinical stage of USCC have an impact on poor outcomes despite the use of standard treatment methods, adapted for cervical cancer. The outside-pelvic failures tend to seek effective systemic treatment.

[Twenty years long experience in the breast conserving treatment of women with preinvasive breast cancer. Evaluation of long term results and analysis of prognostic factors.] / Dwadziescia lat doswiadczen w leczeniu oszczedzajacym u kobiet chorych na przedinwazyjnego raka gruczolu piersiowego. Ocena odleglych wyników i analiza czynników rokowniczych.

AIM: The aim of the study was to analyze long term results and prognostic factors in women with preinvasive breast cancer (DCIS - ductal carcinoma in situ) who underwent breast conserving surgery with subsequent radiotherapy. MATERIALS AND METHODS: A total number of 106 patients was analyzed aged 29-78 years; mean age was 54,3 years and median 55 years. In 78 (73,5%) patients the tumor was diagnosed incidentally on mammography or ultrasound scan, 28 (26,5%) had palpable lesion. 57 patients had the tumor in the left breast and 49 in the right one. Most often the tumor was localized in external quadrants, namely in 56 (52,8%) patients. All patients had breast conserving surgery and then adjuvant radiotherapy of the breast in typical doses. For evaluation of survival we used the Kaplan-Meier test and for evaluation of cumulated loco-regional recurrence we have applied the method of competing risks. RESULTS: At present 101 patients are still alive, 85 have no relapse. 15 patients had local recurrence and 8 had another cancer. Five patients died during follow-up period. Overall 15-years survival in analyzed group was 88% and disease free survival was 74%. Of all prognostic factors only the value of Van Nuys index was relevant. Patients who had the index value less than 7 had significantly worse prognosis than patients with value 7 or more (p=0,043). CONCLUSIONS: At present 101 patients are still alive, 85 have no relapse. 15 patients had local recurrence and 8 had another cancer. Five patients died during follow-up period. Overall 15-years survival in analyzed group was 88% and disease free survival was 74%. Of all prognostic factors only the value of Van Nuys index was relevant. Patients who had the index value less than 7 had significantly worse prognosis than patients with value 7 or more (p=0,043).

GROWTH RATE OF PARAGANGLIOMAS RELATED TO GERMLINE MUTATIONS OF THE SDHX GENES.

OBJECTIVE: The purpose was to determine the growth rate of succinate dehydrogenase subunit (SDHx) gene-related paragangliomas based on computed tomography (CT) measurements. METHODS: Twenty-seven patients with SDHx mutations who underwent subsequent CT examinations were enrolled in the study. Tumors were classified as head and neck (HNP), thoracic, or abdominal/pelvic paragangliomas (PGLs). The percentage volume increase and volume doubling time were estimated. RESULTS: We analyzed 56 PGLs (21 with SDHD, 6 with SDHB mutations) in 27 patients (16 men, 11 women; mean age 37.7 years). The estimated median of the follow-up was 23 months. Twenty-two (39.3%) PGLs were located in the abdomen, 8 (14.3%) in the thorax, and 26 (46.4%) in the head and neck region. The median volume growth rate was estimated at 10.4% per year (interquartile range [IQR]: -1.3; 36.3). The volume doubling time was estimated as 7.01 (2.24;+∞) years. By tumor site, the estimated medians of the annual volume growth rates were 13.6% (IQR:0.8 -30.4) for HNP, -6.06% (IQR: -1.79;47.32) for thoracic PGLs, and 10.5% (IQR: -2.2;44.6) for abdominal PGLs. The volume doubling time was 5.44 years (2.61; 87.0) for HNP, 11.8 years (1.79;+∞) for thoracic PGLs, and 6.94 years (1,88;+∞) for abdominal PGLs. There was no significant difference in the volume growth rate according to tumor location or initial size (P>.7 and P = .07, respectively) or gene mutation type (SDHB vs. SDHD, P>.8). CONCLUSION: PGLs related to SDHx mutations are slowly growing tumors. There were no correlations between tumor location, growth rate or initial size over a 23-month follow-up period. ABBREVIATIONS: CT = computed tomography HNP = head and neck paraganglioma IQR = interquartile range PGL = paraganglioma PPGL = pheochromocytoma and paraganglioma SDH = succinate dehydrogenase.

Radiotherapy in testicular germ cell tumours - a literature review.

Testicular germ cell tumours (GCT) represent about 1-2% of malignant in men. The essential therapeutic option for early-stage GCT is radical orchiectomy (RO), except in situations that require immediate chemotherapy in patients with a massive dissemination and unequivocally elevated levels of tumour markers. Postoperative radiotherapy (PORT) in patients with testicular seminoma in Clinical Stage I (CS I) is one of the treatment options next to active surveillance (AS) and chemotherapy (CHTH). Regardless of the procedure, five-year survival in this group of patients ranges between 97% and 100%. In the article, we present the literature review pertinent to therapeutic options, with a focus on radiotherapy. We have searched MEDLINE (PubMed) for all studies on patients with GCT treated with radiation therapy during the last 20 years, and the current therapeutic recommendations. We used the following keywords: germ cell tumours, testis, seminoma, non-seminoma, radiotherapy, outcome.

The Evaluation of Risk Factors Associated With Relapse and Recurrence of Borderline Ovarian Tumors With Long-Term Follow-up.

OBJECTIVE: The goal was to analyze the risk factors of relapse and to compare the type of recurrence in patients with borderline tumors treated and followed up in Oncologic Center in Warsaw. MATERIALS AND METHODS: This is a retrospective-prospective cohort study of 307 patients with confirmed borderline ovarian tumors treated in the Maria Sklodowska-Curie Memorial Cancer Center in Warsaw between 1994 and 2010. Univariate and multivariate analysis as well as Kaplan-Meier estimates were used to explore the impact of different covariates on progression-free survival. The analysis included the following potential prognostic factors: age, CA 125 value, stage according to classification of the International Federation of Gynecology and Obstetrics (FIGO), methods and radicality of operation, staging, tumor capsule rupture, histopathology, implants, ascites, and microinvasion. The analysis of relapses was also performed. RESULTS: Univariate analysis showed the negative impact of 2 factors on progression-free survival: FIGO II/III (implants) (P = 0.011) and ascites (P = 0.027). The multivariate analyses showed the detrimental effect of FIGO Ic (HR, 2.63; 95% confidence interval [CI], 1.12-6.17, P = 0.027), FIGO II or III (implants) (HR, 3.67; 95% CI, 1.56-8.61, P = 0.003), and incomplete staging (HR, 3.63; 95% CI, 1.09-12.07, P = 0.035), but not ascites (P > 0.1). Relapse occurred in 32 (10%) patients: in 22 patients as borderline and in 10 patients as invasive tumor. Seven (70%) patients with invasive relapse died of disease. All patients with borderline relapses were successfully managed by second surgery, which in 80% was again conservative. CONCLUSIONS: Relapses in borderline ovarian tumor are uncommon, in 10% of patients. Invasive relapses are rare, only in 3% of patients, but often with fatal course irrespective of the treatment applied. The most important clinical risk factors of relapse are implants (FIGO II/III), FIGO Ic, and incomplete staging and this patients as well as patients with ascites should be closely followed. Relapses of borderline histology are easily detected and successfully managed by surgery.

Hypofractionated accelerated radiotherapy in T1-3 N0 cancer of the larynx: A prospective cohort study with historical controls.

AIM: The goal of this prospective study was to assess the effectiveness of a hypofractionated accelerated regime in treatment of the larynx cancer. BACKGROUND: Multiple radiotherapy delivery regimes are used for treatment of the larynx cancer. Hypofractionated regimes could provide similar results with reduced use of radiotherapy facilities. MATERIAL AND METHODS: 223 patients with squamous cell carcinoma of the upper or middle larynx have been treated with 63 Gy delivered in 28 fractions of 2.25 Gy during 38 days, 5 fractions per week. The study endpoints were overall survival, progression-free survival, early and late treatment toxicity. Standard and accelerated radiotherapy groups from the study published by Hliniak et al.20 served as controls. RESULTS: Five-year actuarial overall survival was 87.5% in the study group, 84.5% in the control group receiving accelerated radiotherapy (33 fractions of 2.0 Gy, 6 fractions per week) and 86.2% in the control group (33 fractions of 2.0 Gy, 5 fractions per week). Five-year progression-free survival was 73.6%, 77.2% and 66.2%, respectively. Overall, treatment toxicity and complication rates did not differ between the study group and the control groups. CONCLUSIONS: The hypofractionated accelerated radiotherapy protocol using 5 fractions per week reduced the use of radiotherapy facilities. There was no significant difference in overall survival and progression-free survival between the study and control groups treated with accelerated or standard radiotherapy.

Usefulness of Somatostatin Receptor Scintigraphy (Tc-[HYNIC, Tyr3]-Octreotide) and 123I-Metaiodobenzylguanidine Scintigraphy in Patients with SDHx Gene-Related Pheochromocytomas and Paragangliomas Detected by Computed Tomography.

AIMS: The aim of this study was to assess the usefulness of somatostatin receptor scintigraphy (SRS) using (99m)Tc-[HYNIC, Tyr3]-octreotide (TOC) and 123I-metaiodobenzylguanidine (mIBG) in patients with SDHx-related syndromes in which paragangliomas were detected by computed tomography and to establish an optimal imaging diagnostic algorithm in SDHx mutation carriers. METHODS: All carriers with clinical and radiological findings suggesting paragangliomas were screened by SRS and 123I-mIBG. Lesions were classified by body regions, i.e. head and neck, chest, abdomen with pelvis and adrenal gland as well as metastasis. RESULTS: We evaluated 46 SDHx gene mutation carriers (32 index cases and 14 relatives; 28 SDHD, 16 SDHB and 2 SDHC). In this group, 102 benign tumors were found in 39 studied patients, and malignant disease was diagnosed in 7 patients. In benign tumors, the sensitivity of SRS was estimated at 77% and of 123I-mIBG at 22.0%. The SRS and mIBG sensitivity was found to be clearly region dependent (p < 0.001). The highest SRS sensitivity was found in head and neck paragangliomas (HNP; 91.4%) and the lowest was found in abdominal paragangliomas and pheochromocytomas (40 and 42.9%, respectively). The highest 123I-mIBG sensitivity was found in pheochromocytomas (sensitivity of 100%) and the lowest in HNP (sensitivity of 3.7%). In metastatic disease, SRS was superior to mIBG (sensitivity of 95.2 vs. 23.8%, respectively). CONCLUSION: SRS and 123I-mIBG single photon emission computed tomography (SPECT) sensitivity in SDHx patients is highly body region dependent. In malignant tumors, SRS is superior to 123I-mIBG SPECT.

HDR brachytherapy for the reirradiation of cervical and vaginal cancer: analysis of efficacy and dosage delivered to organs at risk.

OBJECTIVE: To evaluate the efficacy and toxicity of HDR brachytherapy (BT) for the reirradiation of cervical or vaginal cancer arising within a previously irradiated area with a special focus on dosage delivery to organs at risk. METHODS: Twenty consecutive patients with cervical (N = 19) or vaginal (N = 1) cancer were reirradiated with curative intent using BT with or without external beam irradiation and hyperthermia. The median biologically equivalent dose in 2 Gy fractions (EQD2), assuming α/ß = 10, for reirradiation was 48.8 Gy (range: 16.0-91.0 Gy), and the median cumulative EQD2 (for primary treatment and reirradiation) was 133.5 Gy (range: 96.8-164.2 Gy). The median follow-up after retreatment was 31 months (range: 6-86 months). RESULTS: The 3-year overall survival (OS) rate was 68% (95% confidence interval [CI]: 44%-91%). The 3-year disease-free survival (DFS) rate was 42% (95% CI: 19%-65%). The 3-year local control (LC) rate was 45% (95% CI: 22%-69%). For nine patients who received 3D treatment planning, the median cumulative EQD2 to 2 cm(3) of rectum was 94.4 Gy (range: 67.1-118.8 Gy) and to 2 cm(3) of bladder was 99.3 Gy (range: 70.4-122.3 Gy). Grade 3 late toxicity was observed in 3 patients (15%). An interval between primary RT and reirradiation of ≤ 12 months and a tumor diameter >3 cm were significant prognostic factors adversely affecting OS, DFS and LC. CONCLUSIONS: HDR BT is a valuable method for the reirradiation of cervical cancer. A cumulative EQD2 of approximately 100 Gy was safely delivered to 2 cm(3) of the bladder and the rectum.

Which tumour factors preclude organ preservation in patients with rectal cancer?

BACKGROUND: cT3cdT4, cN2, mesorectal nodes > 8 mm, clinically positive lateral nodes, extramural vascular invasion (EMVI) and mesorectal fascia threatening (MRF+) have been utilized as exclusion criteria in several studies on the watch-and-wait (w&w) strategy. Here, our aim was to validate these criteria through a post hoc analysis of two pooled prospective studies on w&w following routine radio(chemo)therapy. METHODS: A review of baseline magnetic resonance imaging was performed in a subgroup of 223 patients treated at a single institution. Of these, 17.9 % started w&w, 12.6 % achieved clinical complete response (cCR) and 9.0 % sustained cCR during median follow-up of 54 months. RESULTS: The multivariable logistic analysis showed that the proportion of circumferential bowel involvement and EMVI significantly influenced the chance of sustained cCR; odds ratios were 0.063 (95 % confidence interval [CI] 0.008-0.489, p = 0.008), and 0.109 (95 % CI 0.014-0.850, p = 0.034), respectively. Sustained cCR was observed in none of the 57 patients with 90 %-100 % circumferential bowel involvement and in only one of the 89 patients with EMVI. In contrast, cT3cdT4, cN2, mesorectal nodes > 8 mm, clinically positive lateral nodes or MRF+ were not independently associated with sustained cCR. Among the subgroups of patients with these features but without (near-)circular tumour or EMVI+, sustained cCR was observed in 12 %-25 % of patients. CONCLUSION: Sustained cCR after routine preoperative radio(chemo)therapy is unlikely in patients with (near-)circular tumour or EMVI, whereas patients with cT3cdT4, cN2, mesorectal nodes > 8 mm, clinically positive lateral nodes and MRF+ should not be denied w&w.

Does pharmacological castration as adjuvant therapy for prostate cancer after radiotherapy affect anxiety and depression levels, cognitive functions and quality of life?

INTRODUCTION: Adjuvant hormonotherapy for prostate cancer patients after radical radiotherapy has a well-established value. However, the impact of such treatment on the patients' quality of life remains to be elucidated. OBJECTIVE: The objective is to assess the impact of adjuvant hormonotherapy with luteinizing hormone-releasing hormone analogue after radical radiotherapy on anxiety and depression levels, cognitive function, sexual function and quality of life of prostate cancer patients. MATERIAL AND METHODS: Two groups of patients were tested: men treated with adjuvant hormonotherapy (88 patients) and men without hormonotherapy (61 patients). Anxiety, depression and cognitive functions were evaluated. Patients answered questions addressing problems linked to hormonal equilibrium. The patients rated their mental status, physical status, quality of life and quality of their relationship. RESULTS: There were no statistically significant differences between patients on hormonotherapy and without hormonotherapy in the level of anxiety and depression (p = 0.844 and p = 0.954) as well as in cognitive function (p = 0.661). Satisfactory sexual performance was preserved in 9/65 patients (14%) on hormonotherapy and the same was applied to 19/49 patients (39%) without hormonotherapy. The difference was statistically significant (p = 0.003). Hormonotherapy was associated with decreased libido (p = 0.031), hot flushes (p < 0.001) and sweating (p < 0.001). No statistically significant differences were found between the groups in the self-rated physical and psychological well-being (p = 0.476 and p = 0.597), quality of life (p = 0.622) and quality of relationship (p = 0.064). CONCLUSIONS: Adjuvant hormonotherapy enhances neither anxiety nor depression, does not impair cognitive function but has a negative effect on the patients' sexual function. It does not worsen self-rated quality of relationship and quality of life.

Obstetric Results after Fertility-Sparing Management of Non-Epithelial Ovarian Cancer.

PURPOSE: To assess the recurrence and birth rates among patients with non-epithelial ovarian cancer. METHODS: The study included 146 patients with germ cell (GCT, n = 84) and sex cord-stromal tumors (SCST, n = 62), who underwent fertility-sparing surgery. Adjuvant chemotherapy was administered to 86 (58.9%) patients. Most cases (133 out of 146) were staged FIGO I. RESULTS: The 5- and 10-year disease-free survival rates were 91% and 83%, respectively. The recurrence risk was not associated with tumor histology, stage or age. Twenty-four months after the treatment, the rate of recurrence was higher than the rate of childbearing. The childbearing rates kept rising after the treatment and exceeded the rate of recurrence after 2 years. The cumulative incidence rates of birth 36, 60 and 120 months after treatment were 13.24%, 20.75%, and 42.37%, respectively. Chemotherapy was not related to childbearing. The patients' age was related to the chance of childbearing. CONCLUSIONS: The prognoses of GCT and SCST are similar. Close follow-ups along with contraception should be offered to women during the first two years after treatment due to the increased risk of recurrence. After this period, relapses are rare and women can safely become pregnant.
