In this report, we present two cases of chronic progressive pulmonary aspergillosis (CPPA) occurring within the irradiated field following SBRT for inoperable stage I NSCLC. Case 1 was a man in his 70 s with a history of smoking and a previous pulmonary resection and SBRT for metachronous primary lung cancer. He received SBRT for T1aN0M0 NSCLC in the right lower lobe as his third primary lung cancer. After 20 months, the patient developed a cough and sputum, and a computed tomography (CT) scan revealed a cavity shadow in the irradiated field, which led to the diagnosis of CPPA. Intravenous voriconazole was immediately started, and after 3 week's administration, the symptoms improved, and the cavity disappeared. After 34 months, the patient died with no recurrence of CPPA and lung cancer. Case 2 was a man in his 80 s with a history of smoking and previous pulmonary resection for lung cancer. He received SBRT for T1cN0M0 NSCLC in the right lower lobe as his second primary lung cancer. After 19 months, the patient developed a fever, and a CT scan revealed a cavity shadow in the irradiated field, which led to the diagnosis of CPPA. Oral itraconazole was administered, followed by diarrhea and anorexia. After 22 days, the patient died. During the follow-up period, there was no recurrence of lung cancer. Risk factors for CPPA include a history of smoking and lung resection, common among candidates for pulmonary SBRT.

Evidence shows that prolactin (PRL) is linked to mammary tumorigenesis, especially in postmenopausal patients, but the data remain controversial. We present a case of a 67 year-old patient with a resistant PRL-secreting PitNET who subsequently developed breast cancer. The patient was known to have persistent high PRL levels despite multimodal treatment (surgery, radiotherapy, and high doses of cabergoline). The tumor specimens obtained after transsphenoidal intervention were histologically and immunohistochemically examined for the following parameters: anterior pituitary hormones, the ki-67 labeling index, CAM 5.2 expression, ER ∝ expression, and somatostatin receptors, which revealed a densely granulated tumor with intense positivity for PRL and ER ∝ , a ki-67 labeling index of 6% and negative MGMT expression. Years later, the patient was diagnosed with breast carcinoma. Histopathological and immunohistochemical examination of the tumor specimen obtained after radical mastectomy confirmed ductal invasive breast cancer with negative immunostaining for prolactin receptors (PLRr) but positive immunostaining for estrogen (ER) and progesterone receptors (PGR) and a ki-67 labeling index of 8%. PRL is involved in mammary development and differentiation, which leads to lactation, the major driver during pregnancy, by regulating ovarian progesterone production. On the basis of the physiological actions of PRL, a role for this hormone in breast cancer has been suggested. Few cases of different types of breast carcinoma associated with hyperprolactinemia due to a pituitary tumor have been reported in the literature.

Four years later, recurrence occurred in the left hilar and mediastinal lymph nodes, necessitating an additional resection. Concurrently, sacral metastases developed and required palliative radiotherapy. Genetic analysis identified an <i>AKT1</i> E17K mutation, characteristic of PSP, and absence of programmed cell death ligand 1 (PD-L1) expression in the tumor. Two years post-recurrence, the tumor recurred in the left mammary gland and mediastinal lymph nodes. Combination immunotherapy with ipilimumab and nivolumab yielded a significantly positive response in this metastatic PSP case. This is the first reported case of successful treatment of multiple distant metastatic PSP with ipilimumab and nivolumab, following the failure of various local treatments. Further case series are warranted to validate the efficacy of immunotherapy in metastatic PSP.</p>","PeriodicalId":13703,"journal":{"name":"International Cancer Conference Journal","volume":"14 1","pages":"60-63"},"PeriodicalIF":0.5,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11695534/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
