One of the main problems regarding the follow-up of patients with brain tumours treated with radiotherapy is the distinction between radiation necrosis and tumour relapse. In many cases computed tomography (CT) scan is unable to distinguish between the two. We assessed the usefulness of brain single-photon emission tomography (SPET) with technetium-99m-sestamibi in cases where CT scan was not conclusive. The absence of tracer uptake in normal brain, the sharp uptake in neoplastic tissue, and the favourable physical properties of technetium make the scintigraphic method particularly accurate. We therefore propose the association of CT scan with 99mTc-sestamibi brain SPET in the follow-up of patients in whom a distinction between radiation necrosis and active disease is needed for an adequate therapeutic decision.

Fifty patients with non resectable and/or inoperable bronchogenic carcinoma were entered into a feasibility study of cisplatin (CDDP) given in continuous infusion with concurrent radiation therapy. The radiation therapy regimen consisted of 2 Gy given 5 days a week in the first 3 and last 2 weeks of a 7-week split course (50 Gy of total dose). The CDDP (daily dose of 4 to 6 mg/mz) was administered to cover the days of radiation treatment by means of a central venous catheter and a portable pump. Less than 1% of predicted duration of infusion was lost due to complications related to venous access and pump. Toxicity was moderate. The overall probability of a locoregional major response (complete + partial) within 1 month after treatment completion was 86%. Twenty-three patients underwent resection. The 1-year actuarial probability of survival was 64%. The high response and survival rates warrant further studies on concurrent CDDP continuous infusion and radiation therapy in inoperable lung carcinoma. Cancer 67:357-362,1991.

Background Italy experienced one of the world’s severest COVID-19 outbreak, with Lombardy being the most afflicted region. However, the imposed safety measures allowed to flatten the epidemic curve and hence to ease the restrictions and inaugurate, on the 4th of May 2020, the Italian phase (P) 2 of the pandemic. The present survey study, endorsed by CODRAL and AIRO-L, aimed to assess how radiotherapy (RT) departments in Lombardy have dealt with the recovery. Materials and methods A questionnaire dealing with the management of pandemic was developed online and sent to all CODRAL Directors on the 10th of June 2020. Answers were collected in full anonymity one week after. Results All the 33 contacted RT facilities (100%) responded to the survey. Despite the scale of the pandemic, during P1 14 (42.4%) centres managed to safely continue the activity (≤ 10% reduction). During P2, 10 (30.3%) centres fully recovered and 14 (42.4%) reported an increase. Nonetheless, 6 (18.2%) declared no changes and, interestingly, 3 (9.1%) reduced activities. Overall, 21 centres (63.6%) reported suspected or positive cases within healthcare workforce since the beginning of the pandemic. Staff units were quarantined in 19 (57.6%) and 6 (18.2%) centres throughout P1 and P2, respectively. In the two phases, about two thirds centres registered positive or suspected cases amongst patients. Conclusion The study revealed a particular attention to anti-contagion measures and a return to normal or even higher clinical workload in most RT centres in Lombardy, necessary to carry out current and previously deferred treatments.
