This phase I/II trial studies the side effects, safety, and effectiveness of low dose radiation to the entire body (total body irradiation \[TBI\]) and higher dose radiation to known areas of cancer (hypofractionated radiation therapy \[H-RT\]) combined with atezolizumab and chemotherapy (carboplatin \& etoposide) in treating patients with small cell lung cancer that has spread to disease sites outside of the lung (extensive stage). Extensive stage disease has historically been treated with chemotherapy alone with consideration of chest (thoracic) radiation therapy for those with response to chemotherapy, as well as consideration of preventative radiation therapy to the head (prophylactic cranial irradiation). Emerging evidence supports the synergistic interactions between immunotherapy and radiation therapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. Combining TBI and H-RT with atezolizumab and chemotherapy may improve response to treatment.

The goal of this clinical trial is to evaluate the safety of TOS-358 in adults with select solid tumors who meet study enrollment criteria. The main questions it aims to answer are:

1. what is the maximum tolerated dose and recommended dose for phase 2?
2. how safe and tolerable is TOS-358 at different dose levels when taken orally once or twice per day?

This clinical trial studies side effects and best treatment time of cryodevitalization in treating patients with early stage (stage I or stage II) lung cancer. Cryodevitalization is a type of cryosurgery that uses a flexible probe (cryoprobe) to kill tumor cells by freezing them. It is delivered at the time of standard diagnostic robotic bronchoscopy. Using cryodevitalization may be safe, tolerable and/or effective in treating patients with early stage lung cancer.

Malignant pleural effusion remains a debilitating complication of end stage cancer, which can be greatly improved by the introduction of the indwelling tunneled pleural catheter (IPC). However, there is no standard of care regarding drainage and limited data on the utility of different drainage techniques. In addition, many patients develop discomfort and chest pain during drainage. The investigators propose to evaluate gravity drainage and suction drainage on quality of life measures and outcomes.

This study is being done to answer the following question: Can the chance of lung cancer growing or spreading be lowered by adding targeted radiotherapy to the usual combination of drugs?

This study is being done to find out if this approach is better or worse than the usual approach for lung cancer. The usual approach is defined as the care most people get for non-small cell lung cancer.

This study is researching an investigational drug called REGN7075 by itself and in combination with cemiplimab with or without chemotherapy. The study is focused on patients with certain solid tumors that are in an advanced stage. The aim of the study is to see how safe and tolerable REGN7075 is by itself and in combination with cemiplimab (with or without chemotherapy), and to find out what is the best dose of REGN7075 to be given to patients with advanced solid tumors when combined with cemiplimab (with or without chemotherapy). Another aim of the study is to see how effective REGN7075 by itself, or in combination with cemiplimab (with or without chemotherapy), is at treating cancer patients.

The study is also looking at:

* Side effects that may be experienced by people taking REGN7075 by itself and in combination with cemiplimab with or without chemotherapy
* How REGN7075 works in the body by itself and in combination with cemiplimab with or without chemotherapy
* How much REGN7075 is present in the blood when given by itself and in combination with cemiplimab with or without chemotherapy
* To see if REGN7075 by itself and in combination with cemiplimab with or without chemotherapy works to treat cancer by controlling the proliferation of tumor cells to shrink the tumor
