Implementation of ultrasonography (USG), computed tomography (CT) and magnetic resonance imaging (MRI) into abdominal cavity diagnostics enabled early detection of cT1 graded renal cancers. According to European Association of Urology (EAU) and Polish urological Association (PUA) recommended method of treatment is sparing resection of renal parenchyma with tumour—nephron-sparing surgery (NSS). In selected cases other methods such as thermal ablation (TA) or cryoablation can be introduced /1/. Objectives: To evaluate the results of treatment of cT1 renal tumours with the use of NSS and TA methods. Material and methods: 140 patients with cT1 renal carcinoma were treated in 2nd Department of Urology of Medical University of Lodz between 2014 and 2017. Neuron-sparing surgery was performed in 56 cases (40%), while percutane-ous thermal ablation (TA) in 84 cases (60%). Demographic data, clinical data (lab results, Charlson index), nephrometry data (tumour size, location, R.E.N.A.L. score) post-operative data (Clavien-Dindo classifica-tion) were investigated. Histopathology results, Fuhrman malignancy grading, as total three-year survival of patients were evaluated. The following methods were used for statistical evaluation: Chi2, Fisher, W Shapiro-Wilk, U Mann-Whitney tests, Kaplan-Meier’s curve and Cox model. The results were displayed in a form of median and upper and lower quartile values (25–75%). Results: No statistical differences in gender nor left/right kidney location were observed. Patients, who underwent TA were at average 10 years older and had multiple comorbidities (median age for TA was 79, for NSS 68; median Charlson index for TA was 5 and for NSS was 3). TA patients had lesser haematological values (Hb, Ht). R.E.N.A.L. scoring demonstrated comparable nephrometry in both groups. NSS procedure was open laparotomy without temporary clamping of renal vessels. Surgical margins of resected tumours were negative. TA was performed with Cool-Tip Covidienequipment with the use of Cluster electrode and was ultraso-nography-guided. Post-treatment complications evaluated with the use of Clavien-Dindo classification were slightly more frequent for NSS method. Patients after NSS were discharged at average after 8.5 days and after TA after 3 days. Histopathological type and Fuhrman malignancy grading were comparable in both groups. TA treated patients’ death risk was 9-fold of that observed in NSS treated patients. There was 1 death for each group in perioperative period. Conclusion: 1. NSS was associated with slightly higher side effect rate but resulted in prolonged survival. 2. TA was applied to elderly patients with comorbidities. Despite less invasive treatment this group had poorer/reduced survival. 3. Charlson Comorbidity Index (CCI) and the treatment method were relevant survival factors in patients treated due to cT1 renal cancer tumours.

Tumours of the sternum are rare and can be malignant, benign or inflammatory.To determine the clinical, pathological and therapeutic options for tumours of the sternum.We report a series of 30 cases of sternal tumours treated in our institution in the period 2006-2015. There were 10 malignant tumours located in the body of the sternum, 2 in the manubrium (metastases of kidney and thyroid carcinoma) and 18 benign tumours located in different parts of the sternum. Diagnosis was obtained by computed tomography scan of the chest, surgical biopsy or excision of the tumours.Malignant tumours were excised radically. Reconstruction of the sternum was obtained by allogenic mesh (polypropylene) and local tissues (mainly pectoralis major muscle). There was 1 postoperative cardiac death. Patients with malignancy were referred for adjuvant chemoradiotherapy. After 2 years there were 4 cases of recurrence of chondrosarcoma (1 case of local recurrence and 3 cases of pulmonary metastases). Recurrence of other tumors were not observed.The management of sternal tumours is dependent on the histological type and the possibility of surgical excision. Reconstruction of the chest wall can be achieved by autogenic or allogenic materials.Guzy mostka spotyka się rzadko i mogą być one złośliwe, łagodne lub zapalne.Przedstawienie problemów klinicznych, patologicznych i możliwości terapeutycznych dotyczących guzów mostka.Przedstawiono 30 przypadków guzów łagodnych i złośliwych mostka leczonych na jednym oddziale w latach 2006–2015. Dziesięć złośliwych nowotworów mostka było zlokalizowanych w trzonie, 2 guzy przerzutowe (raka tarczycy i raka nerki) w rękojeści, a 18 guzów łagodnych w różnych częściach mostka. Rozpoznanie ustalono na podstawie obrazu tomografii komputerowej klatki piersiowej, biopsji chirurgicznej lub wycięcia guza.Guzy złośliwe operowano radykalnie, usuwając fragment mostka wraz z przylegającymi chrzęstnymi odcinkami żeber. Rekonstrukcje mostka wykonywano siatką alogeniczną (polipropylen) i okolicznymi tkankami (najczęściej mięsień piersiowy większy). Stwierdzono jeden zgon pooperacyjny spowodowany zawałem serca. Chorych z guzami złośliwymi kierowano na chemioradioterapię adiuwantową. Po 2 latach odnotowano 4 przypadki nawrotu chrzęstniakomięsaka (wznowa miejscowa w 1 przypadku i przerzuty do płuc w 3 przypadkach). Nie obserwowano nawrotu innych guzów.Leczenie guzów mostka zależy od ich typu histologicznego i możliwości chirurgicznego wycięcia. Rekonstrukcje ściany klatki piersiowej wykonuje się za pomocą materiałów autogennych lub alogennych.
