The famous couplet, “Known is a drop, unknown is an ocean,” is true in case of medicine and life in general. Variable histological patterns are encountered in most of the tumors. These unknown tumors with variable histology are always a challenge to treat, especially in the absence of standard guidelines. The mainstay of treatment for the sarcomatoid variant is surgery, and it is shown to be associated with better outcomes. Chakaborthy et al. have presented their findings in a concise and well-defined manner and have definitely achieved the objectives of the study. We appreciate the time and energy spent by the team to analyze and publish their experience. However, as the sarcomatoid variant is rare, and the outcomes are generally poor, we would like the authors to consider if it is possible for them to assess the following outcomes of patients treated with curative intent (41 of the 60 patients):
- In the present study, out of the 41 patients treated with curative intent, 33 underwent surgery as one of the modalities of treatment; among these, of the 24 patients with oral cavity tumors, 23 were treated with curative intent and had undergone surgery. Hence, it would be better if the outcomes were classified based on the tumor subsite, as done in Bice et al.'s study, where the disease-specific survival for tumors of the oral cavity was better than that for tumors of the oropharynx, larynx, and hypopharynx; additionally, hypopharyngeal tumors had the worst prognosis and presented more commonly with distant metastasis
- The authors could consider mentioning the sites of distant metastasis. As per the study by Lambert et al., the lung and soft tissues were the common sites of metastasis
- Two prognostic indicators, namely perineural invasion (PNI) and lymphovascular invasion (LVI) are considered to be associated with aggressive tumors and poor prognosis. Therefore, we request the authors to mention in their analysis as to how many of their subjects were found to be positive for PNI/LVI, as these factors affect the disease-free survival (DFS) and are also associated with local recurrence and metastasis
- As the present study reported a good DFS in patients treated with curative intent, we would also request the authors to mention the time to recurrence/metastasis. According to Mingo et al.'s study, the time to recurrence was 4 months.
