7-hydroxystaurosporine and Topotecan Hydrochloride in Treating Patients With Relapsed or Progressed Small Cell Lung Cancer

Inclusion Criteria:

* Patients must have histologically confirmed extensive stage small cell lung cancer that is incurable but amenable to treatment with chemotherapy
* Patients must have measurable disease as defined by the Response Evaluation Criteria in Solid Tumours (RECIST); they must have either measurable disease outside the field or progression post radiation therapy
* Patient must have received ONLY first-line platinum-based chemotherapy and relapsed or progressed \>= 3 months post completion of therapy (patients with chemo-sensitive disease)
* Patient must have completed any prior chemotherapy at least 3 months before study entry, have completed surgery or radiotherapy at least 4 weeks before study entry and must have recovered from the toxic effects from any prior therapy; patient must not have had more than 40% of their bone marrow radiated
* ECOG performance status =\< 2 (Karnofsky \>= 60%)
* Leucocytes \>= 3 x 10\^9/L OR
* ANC \>= 1.5 x 10\^9/L
* Platelets \>= 100 x 10\^9/L
* Total serum bilirubin =\< 1.5 x UNL
* AST/ALT =\< 3 x UNL (=\< 5 x UNL if documented liver metastases)
* Creatinine =\< institutional upper limit of normal OR creatinine clearance \>= 50 ml/min/1.73m\^2 for patients with creatinine levels above institutional normal
* The effects of UCN-01 on the developing human fetus are unknown; for this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry and for the duration of study participation; contraception should be continued at least 3 months after the last dose of UCN-01; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
* Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

* Patients who have had prior therapy with a topoisomerase I inhibitor (topotecan or irinotecan) will be excluded
* Patients who have had other chemotherapy regimens other than first-line platinum-based chemotherapy will be excluded
* Patients may not be receiving any other investigational agents
* Patients may not be receiving concurrent radiation therapy while on study treatment
* Patients with uncontrolled/symptomatic CNS metastases; routine CT scans are not required to rule these out except when there is clinical suspicion of CNS disease
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to UCN-01 or other agents used in study
* Because of cardiopulmonary toxicity seen in patients on other studies, patients with a history of coronary artery disease and/or symptomatic cardiac dysfunction should be excluded
* Because UCN-01 may cause hyperglycemia, patients with insulin dependent diabetes mellitus will be excluded; patients with diet-controlled diabetes mellitus or those on oral hypoglycemic agents can be entered at the discretion of the investigator
* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
* Pregnant women are excluded from this study because UCN-01 is a serine-threonine kinase inhibitor with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with UCN-01, breastfeeding should be discontinued if the mother is treated with UCN-01; these potential risks may also apply to other agents used in this study
* Because patients with immune deficiency are at increased risk of lethal infections when treated with marrow-suppressive therapy, HIV-positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with UCN-01 or other agents administered during the study; appropriate studies will be undertaken in patients receiving combination anti-retroviral therapy when indicated
* Patients may not have had any other active malignancy in the past 5 years except for cervical carcinoma in situ and non-melanomatous skin cancer
