| Abstract | Background It is important to understand how elderly patients with locally advanced pancreatic carcinoma (LAPC) should be treated, since the number of elderly cancer patients will increase. However, the optimal treatment for elderly patients with LAPC remains unclear. The purpose of this study was to evaluate the efficacy and safety of hypofractionated intensity-modulated radiotherapy (IMRT) with concurrent gemcitabine for elderly patients with LAPC. Methods We retrospectively analysed the data from LAPC patients aged ≥ 75 years treated with hypofractionated IMRT (48 Gy in 15 fractions) with concurrent weekly gemcitabine at our institution from February 2013 to December 2018. Overall survival (OS), progression-free survival (PFS), locoregional progression-free survival (LRPFS), distant metastasis-free survival (DMFS), and the pattern of recurrence and toxicity were analysed. Results Fifteen patients received treatment during the study period. The median age was 78 years (range 75–86 years), and the Eastern Cooperative Oncology Group (ECOG) performance status (PS) of all patients was 0–1. The median survival time (MST) and median PFS were 20.4 [95% confidence interval (CI) 10.3–36.8] and 13.5 (95% CI 6.4–20.3) months, respectively, and the 1-year OS and PFS rates were 80.0% (95% CI 50–93.1%) and 66.7% (95% CI 37.5–84.6%), respectively. The median LRPFS and median DMFS were 15.6 (95% CI 6.4–36.8) and 14.9 (95% CI 7.0–20.5) months, respectively, and the 1-year LRPFS and DMFS rates were 73.3% (95% CI 43.6–89.1%) and 66.7% (95% CI 37.5–84.6%), respectively. Non-haematologic grade 3 toxicity was observed in three cases, of which only one was induced by radiotherapy, whereas grade 4–5 non-haematologic acute or late toxicities were not observed. Conclusions The OS and PFS of elderly patients with LAPC treated using hypofractionated IMRT with concurrent gemcitabine were favourable and without the occurrence of severe toxicity. This treatment strategy is feasible and promising for elderly LAPC patients with good PS. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
