RESUMO

PURPOSE: To compare the postoperative recovery of patients with superior sulcus tumors (Pancoast tumors) following conventional open surgery vs. a hybrid video-assisted and limited open approach (VALO). METHODS: The subjects of this retrospective study were 20 patients we operated on to resect a Pancoast tumor. All patients received induction chemo-radiation followed by surgery, performed via either a conventional thoracotomy approach (n = 10) or the hybrid VALO approach (n = 10). In the hybrid VALO group, lobectomy and internal chest wall preparation were performed using a video technique, with rib resection and specimen removal through a limited incision. RESULTS: There was no mortality in either group. Two patients from the thoracotomy group required mechanical ventilation, but there was no major morbidity in the hybrid VALO group. The operative times were similar for the two procedures. The average length of hospital stay was shorter and the average pain scores were significantly lower in the hybrid VALO group. The incidence of chronic pain was 10 % in the hybrid VALO group vs. 50 % in the thoracotomy group. CONCLUSIONS: Hybrid VALO resection of Pancoast tumors is feasible and safe, resulting in faster patient recovery and a significantly lower incidence of severe chronic pain than open thoracotomy. We conclude that centers experienced with video-assisted lobectomy should consider hybrid VALO surgery as the procedure of choice for Pancoast tumors.

RESUMO

Adoptive cell therapy with autologous tumor-infiltrating lymphocytes (TIL) and high-dose interleukin-2 (IL-2), after nonmyeloablative chemotherapy, has been shown to result in tumor regression in half of refractory metastatic melanoma patients. In the present study, we describe 2 separate clinical protocols. Twelve patients were treated with "Selected"-TIL, as previously reported and 8 patients with the modified version of "Young"-TIL. Selected-TIL protocol required the establishment of multiple T-cell cultures from 1 patient and in vitro selection of cultures secreting interferon-gamma upon antigenic stimulation. In contrast, Young-TIL are minimally cultured T cells with superior in vitro features that do not require further selection. Two of 12 Selected-TIL patients experienced objective clinical responses (1 complete response, 1 partial response). Out of 8 treated Young-TIL patients, 1 experienced complete response, 2 partial response, and 4 patients had disease stabilization. Twenty-one of 33 enrolled Selected-TIL patients were excluded from the protocol, mainly as cultures failed the interferon-gamma selection criteria or due to clinical deterioration, compared with only 3 Young-TIL patients. Expected bone marrow suppression and high-dose IL-2 toxicity were transient. There was no treatment-related mortality. This study vindicates the feasibility and effectiveness of TIL technology and calls for further efforts to implement and enhance this modality. The use of minimally cultured, unselected Young-TIL enables the treatment of most enrolled patients. Although the cohort of Young-TIL patients treated so far is rather small and the follow-up short, the response rate is encouraging.
