Complete Response to Immunotherapy Combined With Chemotherapy in a Patient With Gynecological Mixed Cancer Mainly Composed of Small Cell Neuroendocrine Carcinoma With High Tumor Mutational Burden: A Case Report.
Article in Frontiers in oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Small cell neuroendocrine carcinoma (SCNEC) is rare in the gynecologic tract, which has high invasive and metastatic ability. Due to the aggressive behavior and lack of treatment, patients have an extremely poor prognosis. Here we report a 66-year-old female diagnosed with SCNEC in the gynecologic tract, mixed with endometrioid adenocarcinoma, squamous cell, and adenosquamous carcinoma. A tumor mutational burden of 13.14 Muts/Mb was detected by next-generation sequencing. The patient underwent a palliative operation of total hysterectomy with bilateral adnexectomy but suffered from disease progression in a short time after the operation. Chemotherapy (paclitaxel + carboplatin) combined with immunotherapy (toripalimab) was conducted every 3 weeks, achieving a partial response after 2 cycles of treatment. After 5 cycles of combined treatment, the patient consolidated with monotherapy of toripalimab for about half a year and achieved a complete response. Until December 2021, the patient has achieved 27 months of progression-free survival and maintains a continued complete response. This case is presented due to the rare combination of pathological types and durable response to treatment especially immunotherapy, suggesting the potential value of immunotherapy in SCNEC of the gynecologic tract.
