Finding Another Treatment Option for Stage 4 Lung Cancer: K.C.s Immunotherapy Story

NSCLC is the leading cause of cancer-related deaths worldwide. Brain, bone, liver, and adrenal gland are the most common extrapulmonary sites of distant metastases. 20-50% of NSCLC will present with metastatic disease. Stage IV NSCLC cancer has an overall median survival time of 7-11 months.

In the past, patients with stage IV disease were generally believed to be incurable. Patients with oligometastatic disease represent a distinct subset. After full evaluation, approximately 7% of patients with metastatic disease will have solitary metastasis. There is evidence that in such patients, survival benefit can be achieved with surgical resection.

Accurate clinical staging is of utmost importance before embarking on curative surgery. FDG-PET/CT plays an important role in decision making and should be done if radical treatment is considered. The overall 5-year survival rate is about 28% for patients with satellite nodules and 21% for patients with ipsilateral pulmonary nodules. In patients with brain metastases, surgical resection achieves 5-year survival rates between 11% and 30%, and those with adrenalectomy for adrenal metastases have 5-year survival rates of 26%.

Most of the data on curative management of oligometastatic NSCLC include patient with adrenal metastasis, brain metastasis, and few selected reports of patients with lung cancer with only a malignant pleural effusion and no other metastatic sites who have long-term cures with chemotherapy and surgery.

Will The Nhs Fund An Unlicensed Medicine If My Doctor Wants To Prescribe It

Your doctor can prescribe a medicine outside its licensed use if they’re willing to take personal responsibility for this “off-licence” use of the medicine.

Your local integrated care board may need to be involved, as it would have to decide whether to support your doctors decision and pay for the medication from NHS budgets.

Impact On Treatment Of Early

Because FDA approved nivolumab plus chemotherapy as neoadjuvant therapy just recently, there was general agreement among experts that it may take time for this treatment to be used broadly.

For example, one of the biggest challenges will be ensuring that patients are actually given the option for neoadjuvant therapy, said Christine Lovly, M.D., Ph.D., of the VanderbiltIngram Cancer Center, who specializes in treating lung cancer. Most people diagnosed with early-stage lung cancer dont see a medical oncologist, who would prescribe this treatment, until after theyve had surgery to remove their tumor.

If youre going to do neoadjuvant therapy, you have to be able to plan the timing of it with medical oncologists and with the surgeon, said Dr. Lovly, who was not involved in the trial. Youre going to have to have more coordination of care across multiple medical specialties.

Thankfully, this is a solvable problem, she continued, because successful models of neoadjuvant care already exist.

For other cancers, like breast cancer, they routinely use neoadjuvant care, so there are breast cancer centers where multidisciplinary teams are sitting under the same roof, said Dr. Lovly, who also wrote an editorial on the trial results in NEJM. I think its completely possible to do this for lung cancer, but health care systems are going to have to adapt.

Treatment Of Occult Nsclc

In occult lung cancer, a diagnostic evaluation often includes chest x-ray andselective bronchoscopy with close follow-up ,when needed, to define the site and nature of the primary tumor tumorsdiscovered in this fashion are generally early stage and curable by surgery.

After discovery of the primary tumor, treatment involves establishingthe stage of the tumor. Therapy is identical to that recommended for other non-small cell lung cancer patients with similar-stage disease.

Stage 4 Small Cell Lung Cancer

Frontiers

The second most-common type of lung cancer after NSCLC is small cell lung cancer . SCLC is not typically grouped into numbered stages. Instead, its identified as limited stage or extensive stage.

  • With limited-stage SCLC, the cancer is present in one lung and may have spread to lymph nodes near that lung, but its contained to one side of the chest. If the lung has multiple tumors, the cancer may not be in the limited stage.
  • Extensive-stage SCLC is similar to stage 4 NSCLC in that it is metastatic. SCLC is considered extensive if it has spread throughout the original lung, into the other lung or faraway lymph nodes, or to any other areas of the body.

When Chemotherapy Is Used

Chemotherapy is the main treatment for small-cell lung cancer , but doctors may also use it before or after surgery, or instead of surgery, in non-small-cell lung cancer .

  • Adjuvant therapy is chemo given after lung cancer surgery to treat any remaining cancer.
  • Neoadjuvant therapy is chemo given to shrink the tumor before surgery.

Even elderly people with lung cancer can have this treatment. If youâre unable to have surgery for some reason, you may have chemotherapy along with radiation therapy to shrink your tumor.

Understanding The Nature Of Stage 4 Cancer

A person with stage 4 cancer may not feel ready to face the likelihood of death, which causes them to be willing to try any kind of treatment, even with a small chance of success, according to the study.

Sometimes, doctors do not speak in straightforward terms with patients about the limited chances of success in curing stage 4 cancer. Patients need to ask questions of doctors about the actual chances of recovery when facing stage 4 cancer. They also should ask about the benefits of hospice care, such as those outlined by the Mayo Clinic.

You need to be well enough to have chemotherapy. The most common chemotherapy drug combination used to treat stage 4 nonsmall cell lung cancer is cisplatin or carboplatin with gemcitabine. Other chemotherapy combinations that may be used include: cisplatin or carboplatin and docetaxel

Stages Of Cancer Explained

Going from Stage IV Lung Cancer to Clean Scans

According to Cancer.net, medical researchers created five specific stages of cancer to describe the progression of the disease. Stage 4 is the most advanced and most serious cancer diagnosis.

  • Stage 0: a small cancerous tumor that is easy to remove and has little to no chance of spreading.
  • Stage 1: an early-stage cancer that has not spread to the lymph nodes, resulting in a good chance of a cure.
  • Stage 2: often consists of large tumors that are affecting nearby tissues.
  • Stage 3: consists of large tumors that likely have spread into the lymph nodes.
  • Stage 4: advanced or metastatic cancer that has spread to other parts of the body, including other organs.

A doctor may initially diagnose cancer at any of these stages. Additionally, cancer initially diagnosed at an early stage could progress to an advanced stage if treatment options do not work.

Questioning The Experts May Send You Away Empty

When an oncologist explains whether or not a therapy is “working,” the reality might not be so black and white. Such conventional cancer treatment protocols are laden with “let’s wait and see language.” In simple terms, if an individual lives five years or more from the beginning of treatment, than that treatment for cancer was considered a success, or that “it worked.”

Because we live in an age of information surplus, more patients are questioning such results and asking better questions about their care. And, that is an excellent thing. The actual results with traditional treatments alone are far more ominous than one might think.

  • Clinical trials can be considered as second-line therapy.
  • Chemotherapy

    The use of chemotherapy has produced objective responses and small improvementin survival for patients with metastatic disease. In studies that have examined symptomatic response, improvement in subjectivesymptoms has been reported to occur more frequently than objectiveresponse. Informed patients with good performance status andsymptomatic recurrence can be offered treatment with a platinum-basedchemotherapy regimen for palliation of symptoms. For patients who haverelapsed after platinum-based chemotherapy, second-line therapy can beconsidered.

    Docetaxel

    Evidence :

  • Two prospective randomized studies have shown an improvement insurvival with the use of docetaxel compared with vinorelbine, ifosfamide, or bestsupportive care however, criteria for the selection of appropriatepatients for second-line treatment are not well defined.
  • A meta-analysis of five trials of 865 patients assessing the efficacy and safety of docetaxel administered weekly or every 3 weeks has been reported. In that analysis, the following was shown:
  • Median survival was 27.4 weeks for patients treated every 3 weeks and 26.1 weeks for patients treated weekly .
  • Significantly less severe neutropenia and febrile neutropenia were reported with weekly docetaxel however, no significant differences were observed for anemia, thrombocytopenia, and nonhematologic toxic effects.
  • Docetaxel plus ramucirumab

    What You Need To Know

    • The most common types of lung cancer include lung nodules, non-small cell lung cancer, small cell lung cancer and mesothelioma.
    • Rare lung cancers often don’t originate in the lung.
    • Rare lung cancers vary according to size, recommended treatment options and rate of metastasis.

    The most common types of lung cancer are those found right in the lungs. Other rarer types of cancer may also occur in the lungs and chest wall.

    Types Of Stage 4 Lung Cancer

    Frontiers

    The two main types of lung cancer are non-small cell and small cell. Non-small cell lung cancerthe most common typeappears larger under a microscope than small cell lung cancer and generally has a more positive prognosis than its counterpart.

    Many individuals with either type of lung cancer are first diagnosed when the condition has already progressed to stage 4. The National Cancer Institute estimates that about 40 percent of patients with non-small cell lung cancer are diagnosed with stage 4 disease, and 66 percent of patients with small cell lung cancer are also diagnosed at this stage.

    How Is Chemotherapy Given

    Chemo drugs for lung cancer are typically given into a vein , either as an injection over a few minutes or as an infusion over a longer period of time. This can be done in a doctors office, chemotherapy clinic, or in a hospital setting.

    Often, a slightly larger and sturdier IV is required in the vein system to administer chemo. They are known as central venous catheters , central venous access devices , or central lines. They are used to put medicines, blood products, nutrients, or fluids right into your blood. They can also be used to take out blood for testing.

    Many different kinds of CVCs are available. The 2 most common types are the port and the PICC line.

    Doctors give chemo in cycles, with each period of treatment followed by a rest period to give you time to recover from the effects of the drugs. Cycles are most often 3 or 4 weeks long. The schedule varies depending on the drugs used. For example, with some drugs, the chemo is given only on the first day of the cycle. With others, it is given for a few days in a row, or once a week. Then, at the end of the cycle, the chemo schedule repeats to start the next cycle.

    Adjuvant and neoadjuvant chemo is often given for 3 to 4 months, depending on the drugs used. The length of treatment for advanced lung cancer is based on how well it is working and what side effects you have.

    The Revised International System For Staging Lung Cancer

    The Revised International System for Staging Lung Cancer, based on information from a clinical database of more than 5,000 patients, was adopted in 2010 bythe American Joint Committee on Cancer and the Union Internationale Contre leCancer. These revisions provide greater prognostic specificity forpatient groups however, the correlation between stage and prognosis predates the widespread availability of PET imaging.

    Treatment Of Stages Ia And Ib Nsclc

    In This Section
  • Adjuvant chemotherapy .
  • Adjuvant targeted therapy .
  • Radiation therapy .
  • Chemotherapy and radiation therapy have not been shown to improve survival in patients with stage I NSCLC that has been completely resected.

    Surgery

    Surgery is the treatment of choice for patients with stage I NSCLC. A lobectomy or segmental, wedge, or sleeve resection may be performed as appropriate. Patientswith impaired pulmonary function are candidates for segmental or wedgeresection of the primary tumor. Careful preoperative assessment of the patients overallmedical condition, especially the patients pulmonary reserve, is critical inconsidering the benefits of surgery. The immediate postoperative mortalityrate is age related, but a 3% to 5% mortality rate with lobectomy can be expected.

    Evidence :

  • The Lung Cancer Study Group conducted arandomized study that compared lobectomy with limited resection forpatients with stage I lung cancer. Results of the study showed the following:
  • Areduction in local recurrence for patients treated with lobectomy compared withthose treated with limited excision.
  • No significant difference in overallsurvival .
  • Similar results have been reported from a nonrandomizedcomparison of anatomic segmentectomy and lobectomy.
  • A survival advantagewas noted with lobectomy for patients with tumors larger than 3 cm but not for those with tumors smaller than 3 cm.
  • A study of stage I patients showed the following:
  • There was no difference in operative mortality.

    In some cases, endobronchial laser therapy and/or brachytherapy has been used to alleviate proximal obstructing lesions.

    Evidence :

  • A systematic review identified six randomized trials of high-dose rate endobronchial brachytherapy alone or with external-beam radiation therapy or laser therapy.
  • Better overall symptom palliation and fewer re-treatments were required in previously untreated patients using EBRT alone.
  • HDREB provided palliation of symptomatic patients with recurrent endobronchial obstruction previously treated by EBRT, when it was technically feasible.
  • Although EBRT is frequently prescribed for symptom palliation, there is no consensus about when the fractionation scheme should be used.
  • Although different multifraction regimens appear to provide similar symptom relief, single-fraction radiation may be insufficient for symptom relief compared with hypofractionated or standard regimens, as shown in the National Cancer Institute of Canada Clinical Trials Group trial .
  • Evidence of a modest increase in survival in patients with better performance status given high-dose radiation therapy is available.
  • Patients with stages IIIB or IIIC disease with poor performance status are candidatesfor chest radiation therapy to palliate pulmonary symptoms . For more information, see Cardiopulmonary Syndromes and Cancer Pain.

    Treatment Option Overview For Nsclc

    In This Section

    In non-small cell lung cancer , results of standard treatment are poorexcept for the most localized cancers. All newly diagnosed patients with NSCLCare potential candidates for studies evaluating new forms of treatment.

    Treatment decisions are based on some of the following factors:

    • Knowledge of histologic type.
    • Status and location of lymph nodes by station.
    • Lymphovascular invasion.

    Surgery is potentially the most curative therapeutic option for this disease. Postoperative chemotherapy may provide an additional benefit to patients with resected NSCLC. Radiation therapy combined with chemotherapy can produce a cure in a small number of patients and can provide palliation in most patients. Prophylactic cranial irradiation may reduce the incidence of brain metastases, but there is no evidence of a survival benefit and the effect of prophylactic cranial irradiation on quality of life is not known. In patients with advanced-stage disease, chemotherapy or epidermal growth factor receptor kinase inhibitors offer modestimprovements in median survival, although overall survival is poor.

    The treatment options for each stage of NSCLC are presented in Table 5.

    Types Of Chest Wall Tumors

    Tumors found in the chest wall are also categorized by whether they are primary tumors or metastatic tumors . All metastatic tumors are malignant. In children, most chest wall tumors are primary, while they are more often metastatic in adults. Primary tumors start in the bones or muscles located in the chest wall.

    Sarcomas â tumors that start in bone or muscle tissue, or more rarely in other types of tissue â are the most common type of primary tumor found in the chest wall.
