Histologic transformation of lung adenocarcinoma to squamous cell carcinoma after chemotherapy: two case reports.
Article in Translational cancer research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Squamous cell carcinoma (SCC) transformation of lung adenocarcinoma has been reported to take place after target therapy resistance. The patterns and mechanisms underlying this phenomenon needs to be explored. We present two such patients here. One patient complained of cough and hemoptysis, the other experienced chest tightness. Both were diagnosed as lung adenocarcinoma. They harbored no driver gene alterations and received first-line and adjuvant chemotherapy respectively. After progression several months later, the second biopsy revealed SCC transformation and the gene test still found no gene abnormalities. The diseases stayed stable after treatment of new therapeutic regimens. Then we searched for literature related and found SCC transformation happened at resistance to target therapy or immunotherapy or spontaneously. Our cases suggested this phenomenon could also happen at resistance to cytotoxic drugs. According to the reported cases, a new target therapy or chemotherapy might be effective after SCC transformation. The mechanisms underlying transformation have not been fully elucidated and probably relate to multiple genetic alterations and cancer stem cells. Since the SCC transformation could happen under various circumstances, we recommend lung cancer patients to run the second biopsy after progression and conduct gene tests to elicit the mechanisms.
