Willing and able to comply with the trial and follow-up procedures; 8. Independent inclusion criteria for the two cohorts: - Cohort 1: Diagnosed with non-digestive system solid tumors, including but not limited to lung cancer, breast cancer, urothelial carcinoma, etc., who have not received prior systemic anti-tumor therapy (including neoadjuvant, adjuvant, or first-line therapy for advanced disease), and are scheduled to receive a chemotherapy regimen containing cisplatin or carboplatin; - Cohort 2: Diagnosed with digestive system solid tumors, including but not limited to gastric cancer, colorectal cancer, etc., who have not received prior systemic anti-tumor therapy (including neoadjuvant, adjuvant, or first-line therapy for advanced disease), and are scheduled to receive a chemotherapy regimen containing oxaliplatin.
Exclusion criteria
Exclusion criteria: Anyone meeting any of the following criteria cannot be enrolled in this study: 1. Known allergy to lubiprostone or any of its components; 2. Suspected or confirmed presence of any of the following diseases: active inflammatory bowel disease or diverticulitis, mechanical intestinal obstruction, perforation, toxic megacolon, or intestinal foreign body; 3. Spontaneous bowel frequency >1 time/day with stool consistency meeting Bristol Stool Scale score 6–7, or habitual diarrhea; 4. Major surgery within 4 weeks before the start of study drug administration that has not fully recovered; 5. The planned chemotherapy regimen includes irinotecan or ADC (antibody-drug conjugates); 6. Other serious, uncontrolled concomitant diseases that may affect protocol compliance or interfere with interpretation of results, including active or progressive (severe) infection, uncontrolled diabetes mellitus, cardiovascular or cerebrovascular diseases (New York Heart Association class III or IV heart failure, second-degree or higher atrioventricular block, acute myocardial infarction within the past 6 months, unstable arrhythmia or unstable angina, cerebral infarction within the past 6 months [excluding lacunar infarction]), or pulmonary diseases (interstitial pneumonia, obstructive pulmonary disease, and history of symptomatic bronchospasm), deep vein thrombosis, or pulmonary embolism; 7. Central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects who have previously received treatment for brain metastases may be considered for participation in this study provided that the condition has been stable for at least 3 months, no disease progression has been confirmed by imaging within 4 weeks before the first dose of study drug, all neurologic symptoms have returned to baseline, there is no evidence of new or enlarging brain metastases, and radiation, surgery, or steroid therapy has been discontinued for at least 28 days before the first dose of study treatment. This exception does not include carcinomatous meningitis, which should be excluded regardless of clinical stability; 8. Pregnant or breastfeeding women; 9. Any other disease, metabolic abnormality, abnormal physical examination, or abnormal laboratory finding that, in the investigator’s judgment, reasonably suggests that the patient has a condition or state that makes the patient unsuitable for use of the study drug, or that may affect the interpretation of study results, or places the patient at high risk; 10. Estimated poor compliance with the clinical study procedures.
