With great interest we read the study of Hamaji et al. (1) entitled “Video-Assisted Thoracoscopic lobectomy Versus Stereotactic Radiotherapy for Stage I Lung Cancer” which was recently published in Annals of Thoracic Surgery. With a mean follow-up of 48 months, the authors show that lobectomy performed by video-assisted thoracoscopic surgery (VATS) offers better results than stereotactic radiotherapy (SBRT) in the treatment of patients with pathologically proved non-small cell lung cancer (NSCLC) in early stages.

Nowadays and according to current guidelines the surgery is the best therapeutic option for the treatment of early stages NSCLC (2-4); being the inoperability secondary to the high surgical risk the SBRT main indication. However, they have shown comparable results with VATS/SBRT in retrospective studies with matching cases (5) including studies with patients who were medically operable but refused surgery (6).

The study has been conducted exclusively in patients with NSCLC stage I and IIa potentially resectable who met adequate standards of operability. The paper attempts to analyze if the SBRT can be an elective valid therapeutic option comparable with the surgery and not as alternative when the patient’s general conditions pose an unacceptable surgical risk. Theoretically the SBRT can provide many advantages to the patients: it’s a treatment that doesn’t require hospitalization, preserves more the lung function, could shortened waiting times and recovery of daily life, and the satisfaction degree and acceptance of the patient is greater. It can be especially useful in older patients who often tend to refuse surgery and who are more difficult to cooperate with postoperative rehabilitation measures.

Although at work the VATS group results are clearly better in both overall survival and cause specified as the recurrence rates, we consider the probability of lymph node involvement, not objectified in the SBRT group, could be adversely affected the results in this treatment group.

This is particularly important especially considering that different pathological strains are included, and some of them have specially propensity for lymphatic spread. For that reason it may be useful for futures studies include a systematic lymph node biopsy by endobronchial ultrasound (EBUS).

We have observed that in the VATS group they included some patients who had undergone chemotherapy, so it’s difficult to know what is the impact of this factor about the results of this specific group of the study.

Similarly, the fact of the close monitoring of SBRT group was based on a TAC realization while in the VATS group was based on a simple physical examination, makes us think which could be underestimated the recurrence time in the operated patients.

As is the case with sublobar resections, it is difficult to compete with the anatomical lobar resection for obtaining good long-term results. Perhaps the SBRT is the ideal alternative to such resections and could support on similar inclusion criteria.
