Lung Neuroendocrine Tumors With Cushing Syndrome Not Biologically Aggressive

Posted on January 18, 2022 by MaryO

Neuroendocrine pulmonary tumors in people with Cushing syndrome (CS) are associated with increased nodal metastasis, higher recurrence, and lower disease-free survival compared with quiescent bronchopulmonary tumors, according to results from an observational case series published in JAMA Network Open. Researchers said their study shows these tumors are not biologically aggressive and underlying carcinoid biology may not be as important as symptomatic hormonal physiology.

Patients (n=68) with CS who underwent curative-intent pulmonary surgery at the National Cancer Institute (NCI) between 1982 and 2020 were retrospectively reviewed for clinical outcomes on the basis of tumor etiology. Outcomes were compared among groups of patients with adrenocorticotropic hormone-secreting carcinoid tumors who were treated at the National Institutes of Health in 2021 (n=68), Hôpital Européen Georges-Pompidou in 2011 (n=14), the Mayo Clinic in 2005 (n=23), and Massachusetts General Hospital in 1997 (n=7).

Patients who underwent surgery at the NCI were aged median 41 years (range, 17-80 years), 42.6% were men, 81.8% were White, and mean follow-up after surgery was 16 months (range, 0.1-341 months).

Most patients had T status 1a (55.9%). The pathological stages were IA1 (37.3%), IA2 (23.7%), IA3 (1.7%), IIB (16.9%), IIIA (20.3%), or unknown (13.2%).

The patients with typical carcinoid tumors (83.8%) underwent lobectomy (70.2%), wedge (22.8%), segmentectomy (5.3%), and pneumonectomy (1.7%) surgical approaches. Patients with atypical carcinoid tumors (16.2%) underwent lobectomy (72.7%) and wedge (27.3%) approaches. Stratified by surgical approach, lobectomy recipients were younger (P =.01) and more had node-positive atypical carcinoid tumors (P =.01).

After surgery, morbidity occurred among 19.1% of patients; overall mortality was 1.5%.

Disease-free survival at 5 years following surgery was 73.4% (95% CI, 48.7%-87.6%) and 55.1% (95% CI, 26.3%-76.5%) at 10 years. Disease-free survival was 75.4% (95% CI, 49.2%-89.3%) at 5 years and 50.2% (95% CI, 18.3%-75.7%) at 10 years for typical carcinoid tumors and remained stable at 75.0% among those with atypical carcinoid tumors. Median follow-up after surgery was 16 months (range, 0.1-341 months). At the time of last follow-up, 76.4% of the patient population was alive and tumor free.

The overall incidence of persistence/recurrence was 16.2%. Recurrent disease occurred in 7 patients and persistent disease in 4 patients. Only one of this group had an atypical carcinoid tumor. Mean time to recurrence in patients with recurrent disease was 76 months with a median of 55 months.

The adrenocorticotropic hormone-secreting carcinoid cohort from multiple institutions was aged median 39 years, 46.4% were men, 72.3% underwent lobectomy or pneumonectomy, 18.7% had morbidity, and 0.9% mortality. The majority of these groups had typical carcinoid tumors (83.9%) with a mean size of 1.1 cm (range, 0.1-10 cm) and 39.4% had lymph node positivity. Recurrence occurred among 12.6% of patients and persistence among 5.4% of patients. Among the recurrence cohort, 85.7% had typical carcinoid tumors. Time to recurrence was >6 years. Disease-free survival was 73% at five years and 55% at 10 years.

This study was limited by the small group sizes, however, due to the rarity of this cancer it was not possible to include more individuals.

“Ectopic adrenocorticotropic hormone secreting carcinoid tumors with Cushing syndrome appear to be associated with increased metastasis to lymph nodes, higher recurrence (mostly local), and lower overall disease-free survival at 5 and 10 years than quiescent bronchial carcinoid tumors, irrespective of histologic subtype,” the researchers wrote. “Nevertheless, we contend these tumors are not biologically aggressive since these patients have distinct, prolonged survival and delayed time to recurrence.”

The researchers also noted that “the current staging system applied to these tumors raises questions about prognostic accuracy. Extrapolation may suggest that the underlying carcinoid biology may not be as important as the symptomatic hormonal physiology.” They suggested future studies may test “whether a lung-sparing surgical approach coupled with routine lymphadenectomy is an optimal intervention in this scenario when normal endocrine functioning is restored and CS sequelae resolve.”

Patient Develops Cyclic Cushing’s Syndrome Due to Lung Neuroendocrine Tumor

Posted on January 26, 2019 by MaryO

Tumors located outside the pituitary gland that produce the adrenocorticotropic hormone (ACTH) may cause, on rare occasions, cyclic Cushing’s syndrome — when cortisol levels show substantial fluctuations over time.

That finding, based on the case of a patient with ACTH-secreting lung cancer,  is found in the study, “Cyclic Cushing’s syndrome caused by neuroendocrine tumor: a case report,” which was published in Endocrine Journal.

Cushing’s syndrome is characterized by too much cortisol, either due to adrenal tumors that produce cortisol in excess, or because too much ACTH in circulation — resulting from ACTH-producing tumors — act on the adrenal glands to synthesize cortisol.

Cyclic Cushing’s syndrome (CCS) is a rare type of Cushing’s in which cortisol production is not steadily increased. Instead, it cyclically fluctuates, from periods with excessive cortisol production interspersed with periods of normal levels.

The fluctuations in cortisol levels over time pose difficulties for a definite diagnosis. Moreover, the precise mechanism underlying the periodic peaks of cortisol peaks are unknown.

Investigators now reported the case of a 37-year-old man admitted to the hospital due to repeated attacks of dizziness, weakness, and high cortisol levels for two weeks.

Repeated tests measuring the levels of cortisol in the blood and a 24-hour urine free cortisol (24 hUFC) assay confirmed a cyclic fluctuation of cortisol, with levels peaking three times and dropping twice (the standard rule for diagnosing CSC).

Upon hospitalization, he further developed high blood pressure and weight gain.

The patient underwent computed tomography (CT) scans, which revealed the presence of an ACTH-secreting tumor in the lungs, the likely cause of the patient’s Cushing’s symptoms. These type of tumors are called neuroendocrine tumors because they are able to release hormones into the blood in response to signals from the nervous system.

Additional scans detected tumors in the adrenal and pituitary glands, but further analysis revealed they were non-functioning tumors, i.e., as their name indicates, they didn’t release excessive ACTH. The thyroid gland also was positive for a tumor.

The patient underwent resection surgery to remove the tumor located in the lungs and nearby lymph nodes. After the surgery, the levels of cortisol in the blood and urine returned to normal, confirming the tumor as the source of the CSC.

The patient also received surgery to remove his thyroid tumor.

An analysis of the patient’s genomic DNA revealed a novel mutation in the PDE11A gene, which is linked to a rare form of ACTH-independent Cushing’s syndrome called primary pigmented nodular adrenocortical disease (PPNAD) type 2.

Whether the patient developed PPNAD, however, and the contribution of a potential PPNAD diagnosis to the CCS, requires further investigation. “To explore pathogenicity of the genetic mutation, we will still plan for a follow-up visit to this patient,” researchers wrote.

Cushing’s Patients at Risk of Life-threatening Pulmonary Fungal Infection

Posted on June 16, 2018 by MaryO

Cushing’s disease patients who exhibit nodules or masses in their lungs should be thoroughly investigated to exclude fungal infection with Cryptococcus neoformans, a study from China suggests.

While rare, the infection can be life-threatening, showing a particularly worse prognosis in patients with fluid infiltration in their lungs or with low white blood cell counts in their blood.

The study, “Cushing’s disease with pulmonary Cryptococcus neoformans infection in a single center in Beijing, China: A retrospective study and literature review,” was published in the Journal of the Formosan Medical Association.

Cortisol, a hormone that is produced in excess in Cushing’s disease patients, is a kind of glucocorticoid that suppresses inflammation and immunity. Consequently, subjects exposed to cortisol for long periods, much like immuno-compromised patients, are at high risk for infections.

In Cushing’s patients, the most common infections include Pneumocystis jiroveci, Aspergillus fumigatus, and Cryptococcosis — 95 percent of which are caused by C. neoformans.

But while “Cushing’s disease patients are susceptible to C. neoformans, the association between pulmonary C.neoformans and [Cushing’s disease] is poorly explored,” researchers said.

In an attempt to understand the clinical characteristics of Cushing’s patients who develop C.neoformans infections, researchers in Beijing, China, reviewed the clinical records of six patients at their clinical center.

Their analysis also included six other patients whose cases had been reported in previous publications.

Patients had a mean age of 44 and 10 were diagnosed initially with high blood pressure. Seven also had diabetes mellitus.

All patients had elevated cortisol levels in their urine and high levels of the adrenocorticotropic hormone (ACTH). Ultimately, all patients were found to have masses in their pituitary glands, causing the high cortisol and ACTH levels.

Patients complained of lung symptoms, including shortness of breath after physical activity, cough, and expectoration. But they had no fever or signs of blood in the lungs, which could suggest lung infection.

A CT scan of the chest then revealed lung nodules in four patients, and lung masses in five patients. Four patients, including one with a lung mass, also had lung air spaces filled with some material (pulmonary consolidation), which was consistent with pulmonary infection.

After analyzing lung nodule/mass biopsies, lung fluids, or blood samples, all patients were diagnosed with C. neoformans pulmonary cryptococcosis.

For their infection, patients received anti-fungal drugs, including amphotericin-B, fluconazole, flucytosine, and liposomal amphotericin. Cushing’s disease, however, was treated with surgery in 10 patients and ketoconazole in two patients.

Despite the treatments, five patients died during follow-up, including four who experienced co-infections or spreading of the cryptococcal infection and one patient with extensive bleeding after surgical removal of the gallbladder.

Among them, two patients had significantly low white blood cell levels and elevated cortisol levels, and four had infiltration in their lungs, suggesting these are markers of poor prognoses.

Researchers also noted that the patients who received ketoconazole died during in the reviewed studies. They attribute this to ketoconazole’s anti-fungal properties, which may interfere with its ability to manage Cushing’s symptoms.

Given the high susceptibility of Cushing’s disease patients to C. neoformans infections, “pulmonary nodules or masses should be aggressively investigated to exclude” this potentially fatal opportunistic infection, the researchers suggested.

“The infiltration lesions in chest CT scan and lymphopenia seem to be potential to reflect the poor prognosis,” they said.

Cushing’s and Hairy Nipples

Posted on March 3, 2018 by MaryO

Hairy nipples are a common condition in women. The amount of hair on the nipples varies, but some women find that the hair becomes long, coarse, and dark, which can be distressing.

Hairy nipples are rarely a cause for concern and are usually not a sign of any underlying health issues. However, occasionally they can signify something more serious, in which case, it is essential to consult a doctor.

Almost every part of a person’s skin is covered in hair and hair follicles. On certain parts of the body, such as the top of the head, the hair usually grows longer and thicker, while on other parts, it is thin and transparent.

Fast facts on hairy nipples:

  • It is not known how common hairy nipples are or how many women have them.
  • Many women do not report the condition and instead manage it themselves.
  • It is possible for hair that used to be fine and light to turn coarse and dark with age.

Causes of hairy nipples in women

There are several underlying reasons that might cause nipple hairs to grow. These are:

Cushing’s syndrome

Cushing’s syndrome is another condition caused by hormonal imbalance. When it occurs, there is an excess of cortisol in the body. In this case, a person may experience several symptoms, such as:

  • increased hair growth
  • abnormal menstrual periods
  • high blood pressure
  • a buildup of fat on the chest and tummy, while arms and legs remain slim
  • a buildup of fat on the back of the neck and shoulders
  • a rounded and red, puffy face
  • bruising easily
  • big purple stretch marks
  • weakness in the upper arms and thighs
  • low libido
  • problems with fertility
  • mood swings
  • depression
  • high blood glucose level

Cushing’s syndrome is fairly rare, and the cause is usually associated with taking glucocorticosteroid medicine, rather than the body overproducing the hormone on its own.

It is possible, however, that a tumor in the lung, pituitary gland, or adrenal gland is the cause.

Also:

Hormonal changes and fluctuations

Hormonal changes in women can cause many different symptoms, one of which is changes in nipple hair growth and color.

Some common hormonal changes happen during pregnancy and menopause.

However, hormonal changes can also occur when a woman is in her 20s and 30s, which may cause nipple hair to change appearance or become noticeable for the first time.

Overproduction of male hormones

It is possible for hormonal imbalances to cause hairy nipples. Overproduction of male hormones, including testosterone, can cause hair growth, while other symptoms include:

  • oily skin that can lead to breakouts and acne
  • menstrual periods stopping
  • increase in skeletal muscle mass
  • male pattern baldness, leading to a woman losing hair on her head

If overproduction of male hormones is suspected, it is a good idea to make an appointment with a doctor who can confirm this with a simple test.

Polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) occurs because of a hormonal imbalance. PCOS is a condition that affects the way the ovaries work.

Common symptoms of PCOS are:

  • infertility
  • irregular menstrual periods
  • ovarian cysts
  • excessive hair growth in unusual places, such as the nipples

PCOS is believed to affect around 1 in 5 women.

Medication

The side effects of particular medicines can cause unusual hair growth.

Medicines, such as testosterone, glucocorticosteroids, and certain other immunotherapy drugs may cause hairy nipples.

What are the treatment options?

Treatment for hairy nipples is not usually necessary for health reasons.

However, many women with the condition prefer to try and reduce or get rid of the appearance of hair on their nipples for cosmetic purposes.

There are several methods by which they can try and do this:

Trimming the nipple hair

Trimming the nipple hair may be enough to reduce its appearance. Small nail scissors are ideal, and hair can be cut close to the skin. It is essential to do this carefully and avoid catching the skin.

Trimming will need to be carried out regularly when the hair grows back.

Tweezing the nipple hair

Tweezing nipple hair is an effective way to get rid of unwanted nipple hair. However, this option can be painful as the skin around the nipple area is particularly soft and sensitive.

It is also important to bear in mind that the hair will return, and tweezing the hair increases the risk of infection and ingrown hairs.

Shaving the nipple hair

Shaving is another option to reduce the appearance of nipple hair. However, it is advisable to do so with caution to avoid nicking the sensitive skin.

This option also carries an increased risk of developing ingrown hairs and infection.

Waxing

Sugaring or waxing is a good hair removal option, though either one is likely to be painful. A salon is the best place to get this treatment type, as doing this at home may cause damage to the skin. Infection and ingrown hairs are again a risk.

Laser hair removal

These popular treatments can help to reduce the hair growth and slow or even prevent regrowth for a while. However, they can be painful, too.

Laser treatment is by far the most expensive option, as it will need to be performed by a plastic surgeon or cosmetic dermatologist.

Hormonal treatment

If a hormonal imbalance is the cause of hairy nipples, a doctor may prescribe or adjust a woman’s medication therapy to restore a healthy hormonal balance.

Other treatments and how to choose

The above treatments are all commonly used to remove and reduce nipple hair and usually have minimal side effects.

Bleaching or using hair removal cream to treat the condition, however, is not advised as these methods are usually too harsh for this sensitive area and may cause irritation and damage.

At what point should you see a doctor?

Hairy nipples in women are quite common, and there is usually no need to see a doctor. However, if they are accompanied by any other unusual symptoms, it is a good idea to make an appointment.

A doctor will be able to perform tests to determine whether an underlying cause, such as PCOS, is causing the growth of nipple hair. If so, they will give advice and medication therapy to help manage the condition.

A doctor will also be able to advise how to remove nipple hair safely.

Takeaway

For the majority of women, nipple hair may seem unsightly, but it is not a cause for any concerns about their health.

However, because some medical conditions can cause nipple hair to darken and grow, it is important to see a doctor if any other symptoms are experienced.

Nipple hair can usually be easily treated and managed, should a woman choose to try to remove the hair for cosmetic reasons.

ACTH-producing Lung Tumors Hard to Detect, But May Be Cured with Surgery

Posted on December 13, 2017 by MaryO

Ectopic Cushing’s syndrome can be challenging to diagnose, especially when it comes identifying the problem source. But appropriate hormone management protocols, used in combination with advanced imaging methods, may help physicians identify ectopic ACTH-producing tumors.

The findings in a case report of a young man with ectopic Cushing’s syndrome were published in the International Journal of Surgery Case Reports, under the title “Case report: Ectopic Cushing’s syndrome in a young male with hidden lung carcinoid tumor.”

Cushing’s syndrome is caused by high amounts of glucocoticosteroids in the blood. The most common cause is a malfunction of the glands that produce these hormones. In some cases, however, the disease may be caused by tumors elsewhere in the body that have the ability to produce adrenocorticotropic hormone (ACTH).

In half of all Cushing’s patients, ectopic ACTH is produced by small lung cell carcinomas or lung carcinoids (a type of slow-growing lung cancer). But some tumors in the thymus and pancreas also have been found to produce ACTH.

Researchers at Damascus University Hospital in Syria presented the case of a 26-year-old man who had ectopic Cushing’s syndrome due to lung carcinoids.

The patient presented with increased appetite and rapid weight gain for more than a year. These were associated with headache, fatigue, proximal muscle weakness, and easy bruising. He had no family history of hormonal disorder.

Based on the initial physical and symptom evaluation, the clinical team suspected Cushing’s syndrome. Blood analysis revealed high levels of cortisol and ACTH hormones, which supported the diagnosis.

Administration of dexamethasone, a treatment used to inhibit the production of glucocoticosteroids by the pituitary gland, reduced cortisol levels within normal range, but not ACTH levels. This led to the diagnosis of ectopic Cushing’s syndrome.

The next step was to identify the tumor causing the syndrome. The team conducted imaging studies of the brain, chest, and abdomen, but found no tumor.

Because ectopic ACTH is commonly produced by lung cancers, the team then analyzed the patient’s lungs. Again, they failed to detect a tumor.

The patient was discharged with prescription of 200 mg of Nizoral (ketoconazole) once-daily, calcium, and vitamin D. After three months of treatment, he remained stable, with no evidence of symptom improvement.

At this point, the team decided to surgically remove both adrenal glands in an attempt to reduce the hormone levels. Treatment with prednisolone 5 mg and fludrocortisone 0.1 mg once daily was initiated, along with calcium and vitamin D.

Eighteen months later, the patient’s condition worsened and he required hospitalization.

Imaging tests targeting the neck, chest, and abdomen were conducted again. This time, physicians detected a 2 cm mass in the middle lobe of the right lung, which was removed surgically. Detailed analysis of the small tumor confirmed that it was the source of the excessive ACTH.

“ACTH secreting tumors can be very hard to detect,” the researchers stated. “Initial failed localization is common in ectopic ACTH syndrome and it is usually due to carcinoid.”

Cases where the ectopic ACTH production is caused by a carcinoid tumor can be challenging to diagnose because tumors are small and relatively slow-growing. Imaging data is often hard to analyze and the tumors can be confused with pulmonary vessels, the researchers explained.

“In such cases we should first aim to lower blood cortisol medically or through bilateral adrenalectomy to avoid Cushing’s complications,” which should then “be followed up through imaging studies (CT, MRI, scintigraphy or PET) to detect the tumor and resect it, which is the definitive treatment of these patients,” the researchers concluded.
