Cancer	Title	Author	Year	Cases	Results
Thyroid lymphoma	Treatment results and prognostic factors in primary thyroid lymphoma patients	Ozyar 9	2011	87	5, 10 year overall survival 74, 71% and DFS 68,64%. Combined modality treatment improves prognosis for aggressive lymphoma, but does not improve OS and LC in indolent lymphoma
ALCH bones	Adult langerhans cell histiocytosis of bone	Ozyar20	2010	30	Complete remission in 70%. Recurrence rates lower in those treated with surgery and RT
Giant cell tumors of bone	Radiotherapy for marginally resected, unresectable, and recurrent giant cell tumors of bone	Bhatia21	2007	39	5-year local failure rate 21%. 5 year OS 94%. Radiotherapy provided excellent long-term local control
Erdheim-Chester disease	Palliative treatment of Erdheim-Chester disease with RT	Miller22	2006	9	EBRT provided short-term palliation in terms of pain control with most cases experiencing recurrence
Solitary plasmacytoma	Outcomes and patterns of failure in solitary plasmacytoma	Ozsahin23	2006	258	Extramedullary SP had better outcomes with moderate dose RT. Progression to myeloma remains issue with medullary disease
Desmoid tumors	Impact of radiotherapy in treatment of desmoid tumours	Baumert24	2006	110	Post-op RT significantly improved 5-year PFS (47% vs 13% for surgery alone)
Non-small cell lung cancer	Exclusive radiotherapy for non-small cell lung cancer	Gouders25	2003	123	2 and 5 year survival- 34, 8%. 5-year local failure rate for T1,T2 - 42%/82%
Urothelial renal pelvis and ureter tumors	Prognostic factors in urothelial renal pelvis and ureter tumours	Ozsahin26	1999	138	Survival influenced by: Karnofsky performance index, pT- and pN-classification, utereral localization, histologic grade, and existence of tumor after surgery
Papillary serous carcinoma	Outcome after combined modality treatment for uterine papillary serous carcinoma	Goldberg27	2007	138	Radiotherapy reduced pelvic recurrence from 29% to 14%. Suggest conservative surgery followed by adjuvant chemo and pelvic RT
Uterine leiomyosarcoma	ABSTRACT: primary uterine leiomyosarcoma: outcomes and prognostic factors	Franzetti Pellanda28	2001	80	Adjuvant radiotherapy did not improve survival or local control. Brachytherapy increased treatment related morbidity.
Testicular lymphoma	Outcome and patterns of failure in testicular lymphoma	Zouhair29	2002	36	Combined modality treatment improved survival. RT technique or dose did not change outcome
Primary anal canal adenocarcinoma	Management of primary anal canal adenocarcinoma	Belkacemi30	2003	82	Combined RT/CHT resulted in better survival rates. Recommend APR for salvage treatmentonly
